Livy Zeppelin Interpreter 'Cannot Start Spark'

Contributor

I have setup a Livy Interpreter through Zeppelin and am trying to run the simple

%livy.pyspark sc.version

Cannot Start Spark

but to no avail.

%spark

sc.version

res10: String = 1.6.2

however, returns the version just fine.

The livy interpreter configs look like such:

livy.spark.master			yarn-cluster
zeppelin.interpreter.localRepo		/usr/hdp/current/zeppelin-server/local-repo/....
zeppelin.livy.concurrentSQL		false
zeppelin.livy.create.session.retries	120
zeppelin.livy.keytab			/<location_of_keytab>/zsk.keytab
zeppelin.livy.principal			<zeppelin_principal>
zeppelin.livy.url			http://<hostname>:8998

I have followed the instructions provided here https://community.hortonworks.com/articles/80059/how-to-configure-zeppelin-livy-interpreter-for-sec.... in entirety.

The cluster is Kerberized as well as Zeppelin being synced to Active Directory. Also, the Resource Managers are in HA and I am seeing a few errors in the livy log regarding refused connections to :8032 (Default Port for RM Admin) See Below for Stacktrace:

Re: Livy Zeppelin Interpreter 'Cannot Start Spark'

@Colton Rodgers, can you please confirm if 'livy.impersonation.enabled' is set to true? There was a known spark issue ( SPARK-13478) where spark application was hitting GSSException while starting HiveContext when livy impersonation was enabled. Due to this issue livy paragraphs were failing with "Can not start Spark".

Workaround:

remove hive-site.xml from /etc/spark/conf ( on the livy server host)

and set livy.impersonation.enabled to false.

The Livy Logs are showing that the HiveContext is starting fine, but for sanity's sake I tried your method of configuration and after the changes and restarts, it is still outputting the same error.

@Colton Rodgers, can you please share livy interpreter logs ?

Re: Livy Zeppelin Interpreter 'Cannot Start Spark'

While the work around did not work exactly, it pointed us in the correct direction of working with the impersonations and making sure that those were all set correctly. Thank you.
