server side DAG of jobs in YARN

[Radim Kolar]

Is there some support for server side control of DAG jobs? I mean 
something which in Tool creates Jobs and submits them with list of 
dependencies and then exits without waiting for end of jobs. I currently 
have this implemented in client side, i have to wait until all jobs are 
finished before System.exit().

JobControl and ControlledJob is client side thing. I think about Spring 
Batch, it has some limited support for server side DAG.
