Subject [jira] Updated: (HADOOP-1351) Want to kill a particular task or attempt
Date Tue, 03 Jul 2007 16:59:07 GMT

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

Enis Soztutar updated HADOOP-1351:

    Attachment: killTask_v1.0.1.patch


This patch enables killing tasks from JobSubmissionProtocol, and command line. killing tasks
from LocalJobRunner is not supported. 
{{bin/hadoop job -kill-task task_0001_m_000000_0}} 
will kill the task attempt. Only killing task attempts is possible, since killing a task(i.e.
TaskInProgress) will result in job failure. 

I have tested the implementation, and it passes all unit tests, however I think it deserves
more testing. I will shortly add killing tasks from web interface.

>    Affects Versions: 0.12.3
>            Reporter: Owen O'Malley

> 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.
