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

             Summary: Unexpected RegistrationTimeoutException of TaskExecutor
                 Key: FLINK-11137
                 URL: https://issues.apache.org/jira/browse/FLINK-11137
             Project: Flink
          Issue Type: Bug
          Components: TaskManager
    Affects Versions: 1.7.0
            Reporter: Biao Liu
            Assignee: Biao Liu


There is a race condition in {{TaskExecutor}} between starting registering to RM and checking registration timeout. Currently we start RM leader retriever first, and then start registration timeout checking. If registration is fast enough, there is a possibility that registration is finished before starting checking registration timeout. The timeout checking will fail later.

There is a stack trace of exception below:
