Accessing Cassandra with Flink intepreter within notebook
Hi,
we would like to read and write via Flink from and to a Cassandra
Cluster.
Our current Apache Zeppelin compilation contains:
- Apache Flink 1.3.2
- flink-connector-cassandra_2.11-1.3.2.jar is located in the /lib/
folder of the flink installation
A Cassandra DB is running and can be accessed via Zeppelin by using the
Cassandra interpreter.
When using the following import, we get an error:
import org.apache.flink.streaming.connectors.cassandra._
error: object connectors is not a member of package org.apache.flink.streaming
import org.apache.flink.streaming.connectors.cassandra._
Our question is:
What do we have to do to read and write from and to Cassandra by using
the Apache Flink interpreter within a notebook. Does anybody have an
example?
Any help would be great.
Kind regards,
Andre

regarding the needed jars we found out that these have to be placed
in the `lib/interpreter` folder within the zepplin folder.
It would be good to have that in the documentation somewhere.
Regards,
