Github user bzz commented on the issue: https://github.com/apache/zeppelin/pull/1407 Thank you for improvements, @cloverhearts Looks good to me. Although as discussed under [ZEPPELIN-1360](https://issues.apache.org/jira/browse/ZEPPELIN-1360) - this approach have performance implications and this code most probably is going to be removed under [ZEPPELIN-1325](https://issues.apache.org/jira/browse/ZEPPELIN-1325).
