Oracle BDCSCE Upgraded: Zeppelin 0.7 and Spark 2.1

Last week, Oracle Big Data Cloud Service – Compute Edition was upgraded from 17.2.5 to 17.3.1-20. I do not know if the new version is still in testing phase and available to only trial users, but sooner or later the new version will be available to all Oracle Cloud users.

The new version is still based on HDP 2.4.2 but it contains upgrades on two key components: Zeppelin and Spark. Users can now select which Spark version they will use (version 2.1 or version 1.6) when creating the service, and Zeppelin 0.7 installed instead of Zeppelin 0.6. Both of them are important changes.

Introduction to Oracle Big Data Cloud Service – Compute Edition (Part IV) – Zeppelin

This is my forth blog post about Oracle Big Data Cloud Service – Compute Edition. In my previous blog posts, I showed how we can create a big data cloud service compute edition on Oracle Cloud, which services are installed by default, ambari management service and now it’s time to write about how we can work with data using Apache Zeppelin. Apache Zeppelin is a web-based notebook that enables interactive data analytics. Zeppelin is not the only way to work data but it’s surely very friendly for end-users and (as I said before) it’s already installed to our big data cloud service compute edition.

We can create a rule to allow access to TCP port 9995 for accessing Zeppelin directly, or we can use “big data console” provided by Oracle. I’ll prefer the second one because our Ngix proxy will let only authenticated users to access Zeppelin.

After you reach the console, go to the notebooks page. Click “new note”, enter a name and then click “OK” – this will create a new empty notebook, and you’ll start editing it. My new notebook’s name is “MyFirstNote”. As you can see there are some sample notebooks, you can examine them to learn how you can use java and spark with Zeppelin.
