---------------------------

             Summary: Avoid requestPartitionState from JM but always try retrigger
                 Key: FLINK-10319
                 URL: https://issues.apache.org/jira/browse/FLINK-10319
             Project: Flink
          Issue Type: Improvement
          Components: Distributed Coordination
    Affects Versions: 1.7.0
            Reporter: 陈梓立
            Assignee: 陈梓立
             Fix For: 1.7.0


Do not requestPartitionState from JM on partition request fail, which may generate too many RPC requests and block JM.

We gain little benefit to check what state producer is in, which in the other hand crash JM by too many RPC requests. Task could always retriggerPartitionRequest from its InputGate, it would be fail if the producer has gone and succeed if the producer alive. Anyway, no need to ask for JM for help.
