Github user sachouche commented on the issue: https://github.com/apache/drill/pull/1011 +1 I have reviewed the code and overall looks good. My main feedback is that the current implementation doesn't currently support secure clusters (at least didn't see any logic associated with that). Yarn applications have issues staying up for a long time because of ticket renewal limitations. We might want to create another enhancement JIRA to support such use-cases.
