> BPServiceActor is a very important thread. In a non-HA cluster, the exit of the BPServiceActor thread will cause the DN process to exit. However, in a HA cluster, this is not the case.
> I found HDFS-15651 causes BPServiceActor thread to exit and sets the "runningState" from "RunningState.FAILED" to "RunningState.EXITED",  it can be confusing during troubleshooting.
> I believe that the DN process should exit when the flag of the BPServiceActor is set to RunningState.FAILED because at this point, the DN is unable to recover and establish a heartbeat connection with the ANN on its own.
