Arun C Murthy commented on HADOOP-2484:
---------------------------------------

More features:

 * Ability to submit and monitor more than one job in a parallel-manner (independent sub-graphs in a DAG)
 * Ability to have custom notifications at various states
 * Features to re-submit jobs on failures
 * Ability to 'cron' jobs
 * Allow users to track 'progress' of the DAG
 * Allow users to submit templatized configs (same set of jobs run daily)
 * Heh, fancy UI ;-)

> Improve facilities for job-control, job-queues etc.

> Today, Map-Reduce has _some_ support for job-control - basically JobClient provides a facility to monitor jobs, one can setup a job-ending notification and there is {{JobControl}}.

> Looks like users could do more with better facilities for job-control and maybe more advanced features like job-queues etc.
> Lets discuss...
