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

> DN process should exit when BPServiceActor exit
> -----------------------------------------------
>
> Key: HDFS-17504
> URL: https://issues.apache.org/jira/browse/HDFS-17504
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Zilong Zhu
> Assignee: Zilong Zhu
> Priority: Major
>
> 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.
