[jira] [Created] (FLINK-11749) Returns the stored leadership on ZooKeeperLeaderRetrievalService stated

TisonKun created FLINK-11749:
--------------------------------

             Summary: Returns the stored leadership on ZooKeeperLeaderRetrievalService stated
                 Key: FLINK-11749
                 URL: https://issues.apache.org/jira/browse/FLINK-11749
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.9.0
            Reporter: TisonKun
            Assignee: TisonKun
             Fix For: 1.9.0


Currently, such as in {{JobMaster}}, if we stop a {{ZooKeeperLeaderRetrievalService}} and restart it, because the cached node data isn't change, we have to manually flush it.

I propose on {{ZooKeeperLeaderRetrievalService}} stated, get {{ChildData}} from {{NodeCache}} and if the data isn't null, generate LeadershipInfo(Address and UUID) and notify the listener.
