Github user elbamos commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/208#issuecomment-205102505 @bzz thanks! Yeah, I was going to suggest, that getting CI to work reliably is probably something important to the project beyond the scope of this PR. One thing that might offer a quick improvement, is @jeffsteinmetz's suggestion that we stop supporting older versions of Spark (e.g., 1.1, 1.2). That should reduce the random test failures by at least 20%.
