Subject [jira] Created: (MAPREDUCE-1563) Task diagnostic info would get missed sometimes.
Date Fri, 05 Mar 2010 08:38:27 GMT
Task diagnostic info would get missed sometimes.
------------------------------------------------

                 Key: MAPREDUCE-1563
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1563
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
            Reporter: Amareshwari Sriramadasu
             Fix For: 0.22.0


TaskStatus's diagnostic info is reset in TaskTracker.cloneAndResetRunningTaskStatuses() method
while constructing TaskTrackerStatus to send the heartbeat. It is also reset after receiving
the response in TaskTracker.transmitHeartbeat() method.
If any task sets diagnostic info between both the clearStatus() calls, the info is lost.
