Subject [jira] Commented: (HADOOP-2484) Improve facilities for job-control, job-queues etc.
Date Mon, 14 Apr 2008 18:47:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12588704#action_12588704

Amar Kamat commented on HADOOP-2484:

- Facility to re-execute a subgraph. This will fasten the process of incorporating dynamic
config changes since only the related nodes/jobs will be re-run with the changed environment.

facility to monitor jobs, one can setup a job-ending notification and there is {{JobControl}}.

advanced features like job-queues etc.
