             Summary: Running a paragraph from another paragraph and multi-user
                 Key: ZEPPELIN-5649
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-5649
             Project: Zeppelin
          Issue Type: Bug
          Components: spark
    Affects Versions: 0.10.0
         Environment: Spark interpreter (%spark) in Zeppelin 0.10.0 and multi-user environment (with notes in personalized mode).
            Reporter: Jérôme Deshayes


Zeppelin's Spark interpreter ({*}%spark{*}) allows to run another paragraph from the current paragraph using "{*}z.run(paragraphID){*}".

In a multi-user environment (with notes configured in personalized mode), each user sees the same paragraphIDs as the other users.

The problem is that when *z.run(paragraphID)* is called, the target paragraph gets executed but not necessarily in the right session.

For instance, user A may execute "z.run(paragraph2)" from paragraph1. But paragraph2 will be executed in the session of user B instead of user A, if user B happens to be the last one that executed paragraph2.

Hence, *z.run* does not seem to support {*}multi-user{*}.
