If you are interested in Big Data, you surely already know Apache Spark or Apache Cassandra, but do you know Apache Zeppelin ? Do you know that it is possible to draw out beautiful graph using an user-friendly interface out of your Spark RDD and Cassandra queries ? In this session, I will introduce Zeppelin by live coding example and highlight its modular architecture which allows you to plug-in any interpreter for the back-end of your choice. Then we'll dig into the Apache Cassandra interpreter and show how to use it as a default front-end to display your Cassandra data About the Speaker DuyHai DOAN Apache Cassandra Evangelist, DataStax DuyHai DOAN is an Apache Cassandra Evangelist at DataStax. He spends his time between technical presentations/meetups on Cassandra, coding on open source projects like Achilles or Apache Zeppelin to support the community and helping all companies using Cassandra to make their project successful. Previously he was working as a freelance Java/Cassandra consultant.

16. Vanilla Zeppelin + OSS Spark
First add Spark/Cassandra connector as dependency for Spark interpreter in
Zeppelin

17. Vanilla Zeppelin + OSS Spark
Then configure Spark to include the connector dependencies: $SPARK_HOME/
conf/spark-env.sh

18. Vanilla Zeppelin + DSE
Only need to add Spark/Cassandra connector as dependency for Spark
interpreter in Zeppelin

19. Pre-built Zeppelin + OSS Spark
Only need to configure Spark to include the connector dependencies:
