Subject [jira] Commented: (MAPREDUCE-1482) Better handling of task diagnostic information stored in the TaskInProgress
Date Mon, 01 Mar 2010 06:35:06 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12839564#action_12839564

Amareshwari Sriramadasu commented on MAPREDUCE-1482:
----------------------------------------------------

Shall we add a log saying "Received diagnostic info: " +info in setDiagnosticInfo? This would
be at least written to log file before truncation.

> 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.
