Incremental Updates

Hadoop and Hive are quickly evolving to outgrow previous limitations for integration and data access.
On the near-term development roadmap, we expect to see Hive supporting full CRUD operations (Insert, Select, Update, Delete). As we wait for these advancements, there is still a need to work with the current options—OVERWRITE or APPEND— for Hive table integration.

The OVERWRITE option requires moving the complete record set from source to Hadoop.…

Customers’ Hadoop Journey

We’ve all had two weeks to reflect on Hadoop Summit 2014. One of the biggest differences that stood out in this year’s Summit (as compared to Summit 2013) was the presence of large enterprise customers that are using Apache Hadoop as an important part of their modern data architectures.

Hadoop has gone beyond its original Yahoo use case—indexing the web via a nightly batch MapReduce process —and into the mainstream of daily data processing and analytics with real-time, online, interactive, and batch applications at many notable companies.…

Apache YARN Ready Program

With the release of Apache Hadoop YARN in October of last year, organizations are moving from single-application Hadoop clusters to a versatile, integrated Hadoop 2 data platform hosting multiple applications — eliminating silos, maximizing resources and bringing true multi-workload capabilities to Hadoop.

Customers are telling us loud and clear: they want solutions that run on YARN because it enables them to run multiple workloads on the same common data pool.…

More and more solution providers are integrating with Hortonworks Data Platform to provide their customers with enterprise Hadoop.

As part of our HDP 2.1 certification series, I would like to introduce Greg Benson, Chief Scientist at SnapLogic. In this blog, Greg provides some insights about the value of obtaining HDP 2.1 certification and the benefits of integration platform as a service (iPaaS). 

SnapLogic provides a cloud-based service for performing a wide range of data and application integration tasks.…

Apache Ambari has always provided an operator the ability to provision an Apache Hadoop cluster using an intuitive Cluster Install Wizard web interface, guiding the user through a series of steps:

  • confirming the list of hosts
  • assigning master, slave, and client components to configuring services, and
  • installing, starting and testing the cluster.

With Ambari Blueprints, system administrators and dev-ops engineers can expedite the process of provisioning a cluster. Once defined, Blueprints can be re-used, which facilitates easy configuration and automation for each successive cluster creation.…

Since the partnership between Hortonworks and Splunk and the release of Hunk last year, we have created some awesome assets (i.e., Hunk sandbox tutorial, 360-degree customer view webinar) that have enabled Hadoop and Big Data enthusiasts’ hands-on training with Big Data. You can find more details around our partnership and resources here: http://hortonworks.com/partner/splunk/

As part of our HDP 2.1 certification series, I would like to introduce Brett Sheppard, Director of Product Marketing for Big Data at Splunk.…

We recently hosted the fourth of our seven Discover HDP 2.1 webinars, entitled Apache 2.4.0, HDFS and YARN. It was very well attended and a very informative discourse. The speakers outlined the new features in YARN and HDFS in HDP 2.1 including:

  • HDFS Extended ACLs
  • HTTPs support for WebHDFS and for the Hadoop web UIs
  • HDFS Coordinated DataNode Caching
  • YARN Resource Manager High Availability
  • Application Monitoring through the YARN Timeline Server
  • Capacity Scheduler Preemption

Many thanks to our presenters, Rohit Bakhshi (Hortonworks’ senior product manager), Vinod Kumar Vavilapalli (co-author of the YARN Book, PMC, Hadoop YARN Project Lead at Apache and Hortonworks), and Justin Sears (Hortonworks’ Product Marketing Manager).…

Traditionally, HDFS, Hadoop’s storage subsystem, has focused on one kind of storage medium, namely spindle-based disks.  However, a Hadoop cluster can contain significant amounts of memory and with the continued drop in memory prices, customers are willing to add memory targeted at caching storage to speed up processing.

Recently HDFS generalized its architecture to include other kinds of storage media including SDDs and memory [1]. We also added support for caching hot files in memory [2].…
