Data Reporting With Zeppelin


In this tutorial you will be introduced to Apache Zeppelin and teach you to visualize data using Zeppelin.


The tutorial is a part of series of hands on tutorial to get you started on HDP using the Hortonworks sandbox. Please ensure you complete the prerequisites before proceeding with this tutorial.


Apache Zeppelin

Apache Zeppelin provides a powerful web-based notebook platform for data analysis and discovery.
Behind the scenes it supports Spark distributed contexts as well as other language bindings on top of Spark.

In this tutorial we will be using Apache Zeppelin to run SQL queries on our geolocation, trucks, and
riskfactor data that we’ve collected earlier and visualize the result through graphs and charts.

Create a Zeppelin Notebook

Navigate to Zeppelin Notebook

Open Zeppelin interface using browser URL:

Zeppelin Dashboard

Click on a Notebook tab at the top left and select Create new note. Name your notebook Driver Risk Factor.

Zeppelin Create New Notebook

Execute a Hive Query

Visualize finalresults Data in Tabular Format

In the previous Spark and Pig tutorials you already created a table finalresults or riskfactor which gives the risk factor associated with every driver. We will use the data we generated in this table to visualize which drivers have the highest risk factor. We will use the jdbc hive interpreter to write queries in Zeppelin.

  1. Copy and paste the code below into your Zeppelin note.
SELECT * FROM riskfactor
  1. Click the play button next to “ready” or “finished” to run the query in the Zeppelin notebook.
    Alternative way to run query is “shift+enter.”

Initially, the query will produce the data in tabular format as shown in the screenshot.


Build Charts using Zeppelin

Visualize finalresults Data in Chart Format

1. Iterate through each of the tabs that appear underneath the query.
Each one will display a different type of chart depending on the data that is returned in the query.


2. After clicking on a chart, we can view extra advanced settings to tailor the view of the data we want

Chart Advanced Settings

3. Click settings to open the advanced chart features.

4. To make a chart with riskfactor.driverid and riskfactor.riskfactor SUM, drag the table relations into the boxes as shown in the image below.

Advanced Settings Boxes

5. You should now see an image like the one below.

Bar Graph Example Image

6. If you hover on the peaks, each will give the driverid and riskfactor.


7. Try experimenting with the different types of charts as well as dragging and
dropping the different table fields to see what kind of results you can obtain.

8. Let’ try a different query to find which cities and states contain the drivers with the highest risk factors.

SELECT a.driverid, a.riskfactor,, b.state
FROM riskfactor a, geolocation b where a.driverid=b.driverid

Filter City and States

9. After changing a few of the settings we can figure out which of the cities have the high risk factors.
Try changing the chart settings by clicking the scatterplot icon. Then make sure that the keys a.driverid
is within the xAxis field, a.riskfactor is in the yAxis field, and is in the group field.
The chart should look similar to the following.

Scatter Plot Graph

You can hover over the highest point to determine which driver has highest risk factor and where the live.


Now that we know how to use Apache Zeppelin to obtain and visualize our data, we can use the skills
we’ve learned from our Hive, Pig, and Spark labs, as well and apply them to new kinds of data to
try to make better sense and meaning from the numbers!
