Github user WangTaoTheTonic commented on the issue: https://github.com/apache/flink/pull/3599 I don't think it's a good idea, as it can not solve the "split brain" issue too. The key problem is that `LeaderLatch` in curator is too sensitive to connection state to Zookeeper(it will revoke leadership when connection to zookeeper is temporarily broke), and probably the best way is offerring a "duller" LeaderLatch, which can be also used in standalone cluster. I did same work in our own private Spark release, let me see if it can be reused.
