             Summary: There is a big chance that a taskExecutor starts another RegistrationTimeout after successfully registered at RM
                 Key: FLINK-11708
                 URL: https://issues.apache.org/jira/browse/FLINK-11708
             Project: Flink
          Issue Type: Bug
          Components: Distributed Coordination
    Affects Versions: 1.7.2, 1.6.3
            Reporter: Kai Chen


Currently *TaskExecutor.start()* method starts by connecting to the ResourceManager and ends with a *startRegistrationTimeout()* method. However, the *startRegistrationTimeout()* is ** probably ** called after the connection to ResourceManager is established. Then in time of "taskmanager.registration.timeout", *registrationTimeout()* is called and throw a RegistrationTimeoutException bellow, which causes the TaskExecutor shutdown:

Shutting it down... org.apache.flink.runtime.taskexecutor.exceptions.RegistrationTimeoutException: Could not register at the ResourceManager within the specified maximum registration duration 300000 ms.
