Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/2686 Thanks @liguohuicmss for the improvement! I manually tested this branch and it works really well. It seems Jenkins somehow failed to start a build job for this pullrequest. @liguohuicmss Could you try setup [Continuous Integration](http://zeppelin.apache.org/contribution/contributions.html#continuous-integration) and trigger the build? push new commit or close/reopen pullrequest will trigger the job.
