use more than one host with spark cassandra connector
Hi,
is there a way to connect a zeppelin instance to more than one cassandra
hosts via the spark cassandra connector to use the data from them in spark?
BR,
Sebastian.

Try %spark.conf

Hi Jeff,
thank you. Is it possible to change the spark property in a %spark
paragraph which was set interpreter UI or has the interpreter to be
restarted for that?
BR,
Sebastian.

Sebastian,
I don't think spark interpreter of zeppelin does anything for cassandra.
IIUC spark.cassandra.connection.host is spark-cassandra connector property,
as long as spark support it, it should work in zeppelin. So I would suggest
to you to figure out how to set more than one host in spark cassandra
connector first.

Hi Jeff,
thank you for your answer. Zeppelin already does is in the spark
interpreter: set the property spark.cassandra.connection.host , add the
cassandra-connector to the dependencies and go. But where do i configure an
additional host? In the same interpreter. Do i have to add a separate spark
interpreter?
Thank you,
Sebastian.

It is better to ask this kind of question in spark community. As long as
spark support it, you can do it in zeppelin.
