azagrebin commented on issue #8046: [FLINK-12006][coordination] Ensure owned znode deleted on ZooKeeperHaServices#deleteOwnedZNode URL: https://github.com/apache/flink/pull/8046#issuecomment-477139683 @TisonKun thanks for addressing the comment. I think it would be still useful to try to reproduce it on Travis. Do you have a travis activated for your Github account? Could you try it in your Travis? I would loop the whole test suite ZooKeeperHaServicesTest. You could have a look how unstable Kafka unit test is being looped in this commit on my branch in my Travis: https://github.com/azagrebin/flink/commit/6961315f82a82b9810af1f1ba17d45f2bcf82669 You could add the log statements around `deletingChildrenIfNeeded` to make sure that it passes successfully, also in case of test failure if it is reproducable.
