Subject [jira] Commented: (HADOOP-76) Implement speculative re-execution of reduces
Date Fri, 07 Jul 2006 15:36:31 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-76?page=comments#action_12419731 ] 

Johan Oskarson commented on HADOOP-76:

As one should've suspected there seems to be a problem with the patch.
It doesn't clean up after the tasks properly, but I do not currently have the time to look
at this.
Still, feedback is welcome or if someone wants to use any of it in their own patch, go ahead.
