Github user bzz commented on the issue: https://github.com/apache/zeppelin/pull/1689 Thanks for explanation, makes sense to me On CI failures - from my experience, if the reason of failure is posted here - there speeds up the merge dramatically. I have update [ZEPPELIN-1797](https://issues.apache.org/jira/browse/ZEPPELIN-1797) \w Scala 2.10 profile failure on DependencyInterpreter, that is a first failng profile here. And the last one loooks like something new, possibly [related to Livy](https://api.travis-ci.org/jobs/183791719/log.txt?deansi=true), do we have a JIRA issue for that? Other that that - current master build time is `Elapsed time 32 min 6 sec`, this branch `Elapsed time 34 min 4 sec`...
