Key: HADOOP-2484
URL: https://issues.apache.org/jira/browse/HADOOP-2484
Project: Hadoop
Issue Type: New Feature
Components: mapred
Reporter: Arun C Murthy
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...
