Hi Folks, The zeppelin travis become unstable again recently. I know it is really annoying and frustrated, so I create a PR to disable these flaky tests. There still some flaky test, but happens in low frequency. According my experience, if you still have travis build failure after this PR, you can try to rerun the travis build to get travis build pass. Just rerun the failed one, don't run the whole travis build matrix and also please clear travis cache first. If there's no objection, I would commit this PR. And after that, please keep travis build passed before you commit any new changes. Thanks.
