> Reporter: Prasanth Jayachandran

> Provide an option for launching tez AM in unmanaged mode. In unmanaged mode,
> tez AMs can register itself with Zookeeper which clients (like HiveServer2)
> can discover via zk registry client.
> HiveServer2 currently manages the lifecycle of tez AMs. The unmanaged mode
> will let AM come up on their own (can be via simple java launcher) and be
> discoverable for others.
> Example use case for this is, HiveServer2 can discover already running AMs
> and can attach to it for DAG submission and detach when done executing
> queries. AMs can similarly discover LLAP daemons via task scheduler plugin
> for submitting tasks.
> A mode to cut off interactions with RM will also useful since for LLAP no
> on-demand containers are required.
