> Currently, TezJob extends ControlledJob, and TezLauncher submits TezJob to
> the cluster via ControlJob. However, there is no reason for this since
> ControlJob always contains a single job in Tez unlike MR.
> There are some operators such as MergeJoin that consists of more than 1
> disjoint DAGs. But this case is handled by TezPlanContainer. TezPlanContainer
> holds multiple DAGs, and TezLauncher compiles and submits them one by one in
> order.
> I propose we should rewrite TezJob and TezLauncher using ExecutorService.
