I tested the following scenarios:
For failover:
* Submit a unmanaged AM and failover RM, unmanaged AM is able to reregister
and complete successfully. Verified that all it’s containers are preserved and
no work is lost.
For recording state:
* A unmanaged AM that completes successfully and verified state is SUCCEEDED
* A unmanaged AM that is killed during execution and verified state is KILLED
* A unmanaged AM that fails (essentially times out) and verified state is
FAILED

> Currently work preserving RM restart recovers unmanaged AMs but it has a
> couple of shortcomings - all running containers are killed and completed
> unmanaged AMs are also recovered as we do _not_ record final state for
> unmanaged AMs in the RM StateStore. This JIRA proposes to address both the
> shortcomings so that work preserving unmanaged AM recovery works exactly like
> with managed AMs
