> *Problem* Zookeeper is not shut down completely when dataDir disk space is
> full and ZK Cluster went into unserviceable state.
>
> *Scenario*
> If the leader zookeeper disk is made full, the zookeeper is trying to
> shutdown. But it is waiting indefinitely while shutting down the
> SyncRequestProcessor thread.
> *Root Cause*
> this.join() is invoked in the same thread where System.exit(11) has been
> triggered.
> When disk space full happens, It got the exception as follows 'No space left
> on device' and invoked System.exit(11) from the SyncRequestProcessor
> thread(The following logs shows the same). Before exiting JVM, ZK will
> execute the ShutdownHook of QuorumPeerMain and the flow comes to
> SyncRequestProcessor.shutdown(). Here this.join() is invoked in the same
> thread where System.exit(11) has been invoked.
