             Summary: Close the connection between TM and JM when task executor failed
                 Key: FLINK-30505
                 URL: https://issues.apache.org/jira/browse/FLINK-30505
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Task
    Affects Versions: 1.16.0
            Reporter: Yongming Zhang
             Fix For: 1.17.0


When resource manager detects a task executor has failed, it will close connection with task executor. At this time,jobs running on this tm will fail for other reasons(no longger reachable or heartbeat timeout).

If close the connection between task executor and job master when resource manager detects a task executor has failed,the real reason for task executor failure will appear in "Root Exception".This will make it easier for users to find problems.
