> Labels: apex-hadoop-version
>
> On app master failure, the streaming containers should continue running.
> As of 2.2, YARN will automatically terminate all containers and the
> replacement app master will relaunch them. Once we move to a newer minimum
> Hadoop version, we should leverage work preserving restart.
> The mechanism in Apex containers to locate the new master process are already
> in place.
