Gergely Lendvai created ZEPPELIN-3767:
-----------------------------------------

             Summary: zeppelin.spark.concurrentSQL setting is not working
                 Key: ZEPPELIN-3767
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3767
             Project: Zeppelin
          Issue Type: Bug
            Reporter: Gergely Lendvai


Currently setting the zeppelin.spark.concurrentSQL option to true in spark interpreter settings results in the following error:

{code}

As a consequence the %sql option is not working with this setting turned on and no spark sql queries can be run.
