Description
Hey,
We are currently using Zeppelin 0.8 with cassandra interpreter. It's working great.
We tried a migration to Zeppelin 0.9 (same issues with 0.10.0 and 0.10.1), and the same notebooks throws exceptions, eg:
SELECT * FROM system.schema_keyspaces; => java.lang.RuntimeException: Fail to callRemoteFunction, because connection is broken at org.apache.zeppelin.interpreter.remote.PooledRemoteClient.callRemoteFunction(PooledRemoteClient.java:108) at org.apache.zeppelin.interpreter.remote.RemoteInterpreterProcess.callRemoteFunction(RemoteInterpreterProcess.java:98) at org.apache.zeppelin.interpreter.remote.RemoteInterpreter.interpret(RemoteInterpreter.java:208) at org.apache.zeppelin.notebook.Paragraph.jobRun(Paragraph.java:490) at org.apache.zeppelin.notebook.Paragraph.jobRun(Paragraph.java:72)
With some other C* cluster / request we have a NPE, but the same stacktrace.
No more information in the interpreter's log...
Downgrading to Zeppelin 0.8 works fine.
Is there something to do ?
edit: It was tested against a 3.11.1 C* cluster, and for simplicity a local docker container with C* 3.11.1 then 4.0, it all results in the same error.
