Subject [jira] Updated: (HADOOP-1351) Want to kill a particular task or attempt
Date Tue, 17 Jul 2007 21:02:04 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1351?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Doug Cutting updated HADOOP-1351:
---------------------------------

    Status: Open  (was: Patch Available)

I'm re-opening this until Enis and Arun can agree on a solution.  Perhaps we should give folks
the option of either killing or failing tasks?

> It would be convenient to be able to kill a particular task or attempt from the command
line. It would look like:
> bin/hadoop job -kill-task tip_0001_m_000000
> bin/hadoop job -kill-attempt task_0001_m_000000_0
> This would allow the user to tell the system to stop a particular task or attempt without
having to restart a task tracker.
