----------------------------------------
Summary: [C*] Interpreter throw exceptions
Key: ZEPPELIN-5707
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5707
Project: Zeppelin
Issue Type: Bug
Components: Interpreters
Affects Versions: 0.10.1, 0.10.0, 0.9.0
Reporter: Nathan KIENLEN
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:
{code:java}
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){code}
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 ?
