Subject [jira] Updated: (MAPREDUCE-1482) Better handling of task diagnostic information stored in the TaskInProgress
Date Thu, 04 Mar 2010 06:46:27 GMT

Amar Kamat updated MAPREDUCE-1482:
----------------------------------

    Status: Open  (was: Patch Available)

Nicholas,
I am canceling the patch as the latest patch unnecessarily logs the task state-string and
diagnostic information which might affect the heartbeat. I will upload a new patch that will
log only if the state-string/diag-info reachs the max limit.

> Task diagnostic information can be very large at times eating up Jobtracker's memory.
There should be some way to avoid storing large error strings in JobTracker.
