Sorry, I meant "with Zeppelin".
Basically I want to write Java Spark Code in the Zeppelin notebook.
Thank you.

Spark supports Scala, Java, Python & R.
Zeppelin supports the first 3, R support is in progress.

Regarding Q2, it's not really possible currently.

Hello!
I want to evaluate Apache Zeppelin for some experiments in
analytics at my company.
Currently we have a custom setup for Apache Spark on Amazon
EC2. This small cluster is used for two purposes:
1) Routing logs coming from an Apache Flume instance and
writing them to an Apache Cassandra database through Spark
Streaming.
2) Analyzing written logs on Cassandra to produce some
(simple) stats for the data stored on Cassandra (producing
ad-hoc tables with processed results).
I have been asked to produce a simple web app demo to show the
results of the computations stored on Cassandra and I have
thought Zeppelin can facilitate my homeworks.
Now I have some questions, before I even attempt to install it:
1) Can I use Java as the programming language for interacting
with Apache Spark? Or I'm constrained with Scala / Python?
2) Can I export images, graphs, etc. to directly use them into
a separate web app? Would it be difficult? Zeppelin can update
those images interactively as data updates on the tables and
without user intervention?
3) Can I read data directly from Cassandra without any further
processing? I have setup some tables that contains already
processed data, so the idea is to read those tables directly
for showing some graphs (maybe using loading data through
SparkSQL).
Thank you and keep up the good work.
Renato Perini.
