Thanks @zjffdu
cc @prabhjyotsingh - you were saying in [a comment for
ZEPPELIN-3292](https://issues.apache.org/jira/browse/ZEPPELIN-3292?focusedCommentId=16387420&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16387420)
there is some issue in the backend that have caused data duplication and you
made a workaround in the [frontend
here](https://github.com/apache/zeppelin/pull/2835)
Can you please help review if this PR also hopefully fixes that data
duplication in the backend? Not sure if we need a separate PR for that?
IPython/IPySpark is newer in Zeppelin and may have some issues so would be
great to make it rock-solid as I know there are more PySpark users than Spark
users using Scala API..
