New HDP Certified Developer (HDPCD) Performance-Based Exam

Hortonworks is excited to announce that our first hands-on, performance based certification exam is now available! The HDP Certified Developer (HDPCD) exam is designed for Hadoop developers working with frameworks like Pig, Hive, Sqoop and Flume. This new approach to Hadoop certification is designed to allow individuals an opportunity to prove their Hadoop skills in a way that is recognized in the industry as meaningful and relevant to on-the-job performance.

Instead of multiple-choice questions, the exam consists of tasks executed on a live, three-node Hortonworks Data Platform cluster:

Exam Objectives

The exam has three main categories of tasks that involve:

  • Data ingestion
  • Data transformation
  • Data analysis

    • Not yet, but soon! The HDP Certified Java Developer exam is scheduled to be available sometime in June. We are hoping to have the new Administrator exam available sometime in May.

  • Excellent Idea to make the exam based on practical knowledge.
    I currently see that exam can be taken from home unlike other exams where in which you can go onsite/exam center and take up. It would be great if you can provide this exam also onsite/exam center.
    What is the examination success criterion? Like other exams 75%?
    How do you plan to access the exam/score?
    Based on number of tasks done successfully?
    How many tasks will be there in the actual exam?
    Do we have any sectional weigh-age?

    My two cents!

    • Good questions! The ability to take the exam from anywhere at anytime is a huge benefit over trying to schedule and then travel to a testing center. All you need is a webcam and good internet access. We have no plans currently to offer the hands-on exams at a testing facility.

      A passing exam is one where the candidate successfully completes a certain number of tasks. It is not a specific percentage because the exam questions vary from candidate to candidate. You might get 7 tasks while another candidate might get 9. In general, you can expect to see 7 to 10 tasks, depending on the accumulated time it takes to complete the tasks.

      I can’t emphasize enough that the practice exam is an extremely useful study aid. I would highly recommend any candidate to attempt it.

      • What is the success criteria? what if tasks are not executed successfully due to syntax errors? but logic is written in the solutions?

  • For the HDP Certified Java Developer , do I have to take the 4 days course, its really a lot of money on a student budget

    • You do not need to attend our training courses to attempt our certification exams. It is highly recommended, but not required.

  • Is this certification a replacement of previous certification “Hadoop 2.0 Developer Certification”? Is the old one still available? Which one should I take? Any suggestions?

    • Yes – this new hands-on certification exam replaces the old “Hortonworks Certified Apache Hadoop 2.0 Developer” exam. The old certification is no longer available, so you need to sign up for the new exam at http://www.examslocal.com. In order to distinguish the old certification from the new one, we have changed the name to “HDP Certified Developer (HDPCD)”.

      • hello Rich

        so that means ….there is no theoretical or MCQ type q , is it?

        exam task means , do we have to write map-reduce code or we have to write hive queries and so on like this?

        without taking hortonworks hadoop course , is it possible to clear HDPCD exam?

        if we clear the HDPCD exam, do Hortonworks offer employment?

        thanks n warm regards
        Aniket

    • If your console freezes or a technical issues occurs, the proctor will pause the timer so that it does not count as part of your two hours to complete the exam. If you completely lose a connection to the exam and cannot get logged back in for some reason, then we handle that on a case-by-case basis depending on how far into the exam you are and other factors.

  • Doesn’t seem like a good idea, the certification should be about having knowledge not performance of real world task completion basis which is much more advanced thing. It will take a lot of experience than just understanding and there too many complexities and cases when solving real-world problems, One can’t go through all of them and thus will never be fully prepared.

  • It would be great if exam is based on very generic checking of skills sets otherwise it wouldn’t be useful. Just a tool like Sqoop has some 10 different variations for importing and exporting data.

  • Answer to the one of the previous question, didn’t clearly tell how success is concluded in the exam. Take an example of exam with 10 tasks and an examinee was able to complete 7 tasks successfully. Is that a success ?

    We need to clearly define success criteria.

    Thanks.

    -Vipul.

    • The passing percentage is around 70-75%, depending on the number of tasks. For example, 7 out of 10; or 5 out of 7.

  • One of the hardware requirement for xertification is
    ◦A monitor with screen resolution larger than 1600 x 900

    This resolution seems to be to high and not available very easily. What would be the impact if we take test from a low resolution monitor? Will the test start?

    Thanks,
    Arvind

  • Hi

    1. Could you please let us know is the new patterns on Live yet? Can we take up the exam ?

    2. could you please also let us know is it sufficient to prepare the course content which were listed in HDPCD page ?? or do we need to refer any other books/blogs/sites etc.

    3. I understand the Minimally Qualified Candidate meaning but could you please also explain other qualification layers like highly qualified/average/distinction etc ??

    4. Could you please also explain the reason behind the tasks variation between the candidates ?? Is it depends upon the complex levels of the tasks ?? or is it depends upon the time taken to complete the task by a candidate ?? or any other ??

    Thanks in advance.

    Thanks,
    Srikanth D.

  • Hi Rich,

    Can I take this exam from home?
    As its performance based will there be any sandbox we need to download?
    What is the configuration of laptop i.e RAM, CPU, and internet bandwidth required?

    Thanks,
    Vittal Jadhav

    • No. Each task is worth 1 point, and a task must be complete and execute properly for it to be marked as successful.

  • I just completed a bunch of tutorials on HDP 2.3 sand box. But just noticed the exam uses 2.2. Will there be much differences between the two? Should I get 2.2 to prepare or I can just fine to go? I will need some time to learn more of course.

    • Nian,
      The Pig, Hive, Sqoop, etc. syntax does not change significantly between HDP versions. As long as you stick to the basics, and don’t use new features of those tools, the only problems you may run into by using a newer HDP version are deprecated syntax. Deprecated doesn’t mean it won’t work, just that there is now a newer way to achieve the same goal.
      As long as you reference the provided documentation on the exam and from https://hortonworks.com/training/class/hdp-certified-developer-hdpcd-exam/, you should be fine.

    • Yes – that would be very inconvenient. You would have to scroll the window through the entire exam. You need a higher resolution – I would recommend an external monitor.

      • Had a chat with the one of the examlocal.com help chat guys,he said laptop with 1366 * 768 resolution is absolutely fine.
        Also my laptop passed the compatibility test on their site with 1366*768 resolution.

        So I am still confused if I can take the exam on my laptop.

      • Hi,

        Is the Live exam as slow as the practice exam(AWS Mock Exam) ?
        The VNC viewer took 2 seconds for me to refresh whenever I used to fire any command.I found it bit annoying and slow. Please let me know

        Regards,
        Rajesh

  • I have did the test in Amazon AWS. I noticed in the Ambari in AWS there is no views (hive, pig, HDFS files or local files). So I did all the exercises in the terminals using commands. Is this intended (to force testers to use commands and typing instead of GUI and mouse operation)? If so, why there is a Ambari shortcut there, what’s that for?

  • Would it be a problem if I use a laptop with 1366 * 768 screen resolution for taking the exam? and I can’t set it to 1600×900.
    and also i dont have any external monitor ,I know it would be inconvenient , but my question is still am able to use 1366*768 Screen resolution for my exam or not?

  • How do you save pig scripts from the command line? I’m doing the practice exam but I don’y know how to save the script into the solutions directory. If I try and create a file manually in the local file system through “filemanager” I get permission denied.

    Can you advise please?

  • Hi,

    I was looking for Pig and Hive certification on examslocal.com, but I can’t find exam there when I search “Hortonworks” nothing appears.

  • hello Rich,

    I am not able to connect EC2 for hdpcd practice exam . the instruction is given in the web is for MAC os. but I am planning to connect Window.

    Kindly share the docs for how to connect ec2 from windows HDPCD Practice Exam.

    Thanks
    PRabu

    • Not books, but you can use the online documentation for Pig, Hive, Sqoop and Flume. You can see exactly what is available by taking the practice exam. You can not use notes or books or have anything on your desk in front of you during the exam.

      • Hello Rich,

        I had prepared my notes on google docs for every topic for a better understanding which carries the syntax as well and the significance of every argument/parameter. Is it allowed to be used for ready reference through the examslocal.com or my local browser.

  • Practice Exam has only one Task, how many should we expect in the real exam ?
    How we supposed to submit the code and output details ? as these details we will required while verifying the work in exam ?

    Thanks, -Nitin

  • HI There,

    you mentioned in the above that we will be able to refer the documentation during the exams, will the same set of documentation which are present on the practice exams also be available in the actual practical exam that we take. I still havent taken the practice exam , thats the reason this question has poped up.

    Thanks,
    Yuvaraj

  • Hi,
    Yesterday(September 21, 2015) I appeared for hortonworks developer certification with following details. I encountered error “unable to resolve dns” due to which proctor had to cancel the exam. He told me hortonworks will contact me and I need to reschedule the exam. I see my exam marked as “System Error” on my examslocal account.

    Can you please let me know how much time will it take to reschedule the exam and what would be the resolution if I encountered same error again? Will I get same time slot or I need to choose again?

    Please reply asap.

  • Hi Rich,

    Do we have to run the given task and produce the result or just write the solutions for the tasks provided. Also, would it be allowed to run the tasks if we need to and after we are satisfied write the solutions for review.

  • Hi Rich,

    I have given my HDP certification for Pig and Hive yesterday (23/09/2015). When can I expect my results? Can I check it online or it will be delivered through mail only?

  • Hi Rich,
    In Test Exam, Document links to Pig, Hive etc does not open in browser. Is there any proxy settings. In Real Exam also We will have access to virtual instance by VNC Viewer ? Document links are not opening as there is no internet access. Thank You

  • Hi Rich,

    I have taken exam recently. The exam screen is not displayed properly. But my screen resolution set as per the instructions and also instructor checked. But it’s not display properly.

    Thanks

      • One month old comment is still waiting for approval ! I need answer to this please. As I need to plan my exam

        My Question:
        While trying Practice Exam on Amazon EC2, I observed an Issue. I am not able to open the documents link. But when I try to open google, gmail etc it works perfectly. It is stated that other access are blocked and only documentation links are open. However I feel its otherway around. How can I be sure that if i need I will be able to access documentation link in real Exam. Please reply. Thanks !

  • Hi Rich,

    I appeared for Exam via examslocal.com. The compatibility tool gave go ahead for Internet bandwidht. I could type and communicate well with Proctor over my browser. But in VNC – that is for Actual Exam each key stroke was taking more than 2 -4 seconds !! I had horrible experience. Proctor asked me to refresh window, Reconnect etc . All tried and no luck. I was so confident that I am aware of all the concepts, but for Syntax when I started looking for Document I felt Its useless to have document access. for me Practice Exam VM was faster. I am sure there was some VM provisioned with Low Memory. I am not happy with this experience and It has impacted my attempt. I gave exam half an hour before – very much disapointed with such experience. I have good internet speed, Streaming videos working fine. I am sure about VM issue but in 2 hours what options you have once you pay for exam ? I am not sure if Examslocal has control over provisioning cloud machines or what ?

  • In the real exam, are we going to write everything on the terminal like window or will we have hue based window.
    and second question: according to the tasks given for HDPCD exam there is no mention of mapreduce and yarn. So is it just Pig, hive, sqoop and flume or we can expect questions from mapreduce and yarn also in the exam…

    • The exam is run on an environment with HDP installed, which does not include HUE. Code can be written using gedit or vi, then executed from a command line. I would highly recommend taking the practice exam to familiarize yourself with the environment.

      You should be able to perform all of the exam objectives listed on our website, and keep in mind that the exam consists of tasks, not questions. When you execute a Pig script, that runs a MapReduce job on YARN, so it is hard to answer your second question because I am not sure what exactly you are asking. You do not have to write any Java code, if that is your question.

      • Hi Rich,

        In the exam is it possible to have tasks specifically based on mapreduce or yarn so is it just limited to pig, hive, sqoop and flume

      • HI Rich Raposa,
        How are you? I just wrote the exam. The questions are fine. I wrote the exam today. Even though my laptop screen is big with max resolution settings of whatever the exam recommended 1600X900, it is very uncomfortable to move the screens up and down.

        On the other hand the GUI which displays the exam is occupying more than 1/4 of the display, when the examiner needed to communicate with the examine through chat window it comes up right disrupting the flow. I have a huge doubt once the window which displays the questions if accidentally closed , is it easy to navigate back into it. The window displaying questions has a corner closed button and no minimize and max buttons shown to play with it

        Getting used to the display environment/getting used to GUI seems taking little time which is at the cost of time expense in two hour window with is playing a drag effect on thinking in successful execution of the exam.

        I wrote all the the questions and saved in the scripts, while executing due to minor syntax errors not able to ace them. I am not sure how the examiner (horton) will evaluate them. will they see the scripts or not. I guess if the same exam is written at a client location with no GUI constraints that would be wonderful.

        And execution on cluster is always good but debug on syntax error on minor issues sometimes takes time. I am positive that there are only minor errors .what is hard rule to say that a examine wrote it successfully? I hope you are employee of horton networks who is in charge of HDPCD certification division and understand the above written. Hope the examiner who is correcting them does understand the hard parts.Again i wrote all the questions given but how far will i go.

  • Does online training available for HDP developer in Hortonnetworks?
    Would you please suggest , how I can register for online training and how I can setup a test environment for my study purpose, before taking the demo certificate test.

    • It depends on the EC2 instance you choose. 3.x costs about 0.3$ while the recommended 3.2x costs about 0.55$ per hour. I used both and found 3.x works fairly good.

  • If I register for the exam and paid the fee of $250.What if I fail for the first time and how many times can I take the exam with the same fee and how many days is it valid? and also the certification?

    • The cost of the exam is $250 per attempt. You can attempt the exam as many times as necessary. The certification is valid indefinitely, but keep in mind your digital badge shows which version of HDP you passed the exam on. So over time, we expect candidates will want to update their certifications every few years as Hadoop evolves and grows.

  • Hi, how would I access the HDFS and MR UI when doing the certification exam. When doing the practice exam, I couldn’t understand how do I access these UI, in case I dont want to validate HDFS filesystem through terminal.

  • Hi,
    I am new to Big data and aspire to do HDPDC Certification. However when doing practice test, I could find any HDFS file browserUI and Job Browser UI on Ambari. It is very essential to see HDFS file structure and Job UI. Can you please guide as to how I can access these UI on the practice and the real exam.

  • Hi,
    How many Tasks will be there for HDP – Java certification, in the the practice exam there is only one task, if there is only one task in real exam then how is the passing score calculated?

  • Hi,
    I am planning to give HDP CERTIFIED DEVELOPER exam. Can you please suggest any reference material or “HDP DEVELOPER: APACHE PIG AND HIVE” program is enough for the exam?

    Thanks.

  • Hello,

    I wrote my HDPCD exam on last Friday 09/09/2016. When can i except the results and how will I receive the results?

    Thanks
    Arun

  • i faced lot of issues while taking the exam i have asked proctor many times but reply was not immediate and connection was lost at your end den whatever i did all tasks were not saved which wasted lot of time.i have dropped message to support team.please do reply me any solution?

  • I took a exam yesterday, I faced at least 6 -7 times connection lost while taking exam. I wasted time and flow of working got distributed many times, in fact I got only 5-10 grace time though the system got interrupted multiple times. one point of time really I felt its waste of time taking exam at Horton work.

  • Hi,
    I passed the exam today and I had a problem with the screen size. Even I changed the resolution to 1920*1080 or 1600*900, it did not help to expand the exam screen to full screen (my window screen size). The exam screen size is just half of my window screen. It appeared as a small window in the center of the examlocal siteweb. Is this normal? Did I miss something? That bothered me so much to see the small screen during the exam.

  • For HDPCD practice exam, I can not connect to AWS instance with VNC view at my office. (I can do it at home). Maybe the firewall of my company network blocked 5901 port. Will this be my problem for actual exam if I’ll pass it in my office?

  • Hi,

    I have 2 questions.

    1.
    My laptop has screen resolution 1600 x 900. Would it fit the full screen of the hdpcd aws? I see for the practise exam on aws it fits.
    2.
    Would the laptop webcam be good for the test or do we need a separate one.

    Thank you for your suggestions in advance.

  • Hi Rich,

    Hortonworks being such a renowned framework, How come the resources provided for the certification provided is such worse & cheap. Its just playing with our money & taking away all the confidence & trust.

    i. The test environment was soooo Horrible, that, adjusting to the environment itself will consume time, every mouse stroke is taking 6-7 sec of time to respond.
    ii. There is no option to zoom/make full screen.
    iii. Screen resolution requirement is set to very high. Even if we dont have, why the tool is certifying the hardware requirements ?
    iv. switching tab, minimizing/browsing is ridiculously slow.

    Its such a worse experience. Hortonworks, should seriously think of its own reputation to conduct such tests. If it doesn’t have capability to afford for a better testing environment, why to conduct the test itself ?

    It was not a certification test, rather a test of your patience to check how much time it takes to respond to your every key stroke… Its a test of patience of the students.

    I am really disappointed & lost trust from Hortonworks.

    Guys, I would say, just don’t waste your money & time preparing for Hortonworks certification. Better to go for claudera rather than Hortonworks.

    Here in this blog also, there is no response to every complaint by aspirants. Neither any improvements in providing better & responsive environment for aspirants since almost a year.

    I had raised many complaints regarding the same issue. Even proctor has submitted a report about it. However there is not a single response from Hortonworks certification team.

    Seriously, Hortonworks shpuld be ashamed of its way, it conducts the certification test & steals money from people.

    • I thought I’m alone who has such terrible experience. Yesterday I tried to pass exam provided by HW, it was HORRIBLE! Connection was lost constantly. Proctor was not able to help, he was absolutely useless, actually. Don’t waste your time, money and nerves. Seriously, don’t. I wrote an email to support-team asking give money back

      • Hi Oraz,

        I faced the same problems while giving the exam. It was so frustrating and discouraging. Did you hear back from them? I would certainly want my money back or ask them to reschedule with a better environment.

  • Hortonworks is UNBELIEVABLY TERRIBLE.

    When my exam started in AMBARI interface I had Pig and Hive in red, and datanode was not even live. Took 40 min just to get everything running. Instructions for tasks are confusing and prone to typos. DO NOT PRESS CTRL, or you will have a fun ride with mozilla zooming in and out when you try to scroll a page, but latency is so horrible that it keeps ctrl pressed. Waste of time and money. Also I had a reliable 120mgbit connection, so it was not on my end.

    Adding icing to the cake, when I was finally able to get my pig and hive shells to start, with some help from the HWX team, the dumps would not work AT ALL, even for small data sets, no way to validate my data. But that does not compare to PigStorage being bugged, and refusing to do anything, leading me to believe I had an error in my script and waster time on pointless debugging of correct chunks of code.

    DO NOT WASTE YOUR MONEY, BECAUSE HWX WILL TAKE IT AND SPEND IT ON TORTURING YOU DURING THE EXAM.
