@vijikarthi Thanks for testing. 'SPARK-10872' is expected while default
configuration of sparkcontext creates 'metastore_db' in the same location. If
you configure hive-site.xml to use mysql or something else for it's metastore,
the errors will gone. Alternatively, you can set
'zeppelin.spark.useHiveContext' to 'false' in Interpreter menu, if you're not
relying on HiveQL.
Regarding proxy user support, If passing "--proxy-user" argument in
SPARK_SUBMIT_OPTIONS is the only way, Zeppelin needs extra mechanism to pass
this argument. Thanks for sharing the details and user test result!
