[jira] [Created] (FLINK-14111) Flink should be robust to a non-leader Zookeeper host going down

Aaron Levin created FLINK-14111:
-----------------------------------

             Summary: Flink should be robust to a non-leader Zookeeper host going down
                 Key: FLINK-14111
                 URL: https://issues.apache.org/jira/browse/FLINK-14111
             Project: Flink
          Issue Type: Wish
          Components: Runtime / Coordination
    Affects Versions: 1.9.0, 1.8.1, 1.8.0, 1.7.2
         Environment: Linux

JVM 8

Flink {{1.7.2}}, {{1.8.1}}, {{1.9.0}}

{{Zookeeper version 3.4.5}}
            Reporter: Aaron Levin


I noticed that if a non-leader Zookeeper node goes down and there is still quorom in the zookeeper cluster , my flink application will restart anyway. I believe it should be possible for Flink applications not to require a restart in this scenario.
