Subject [jira] [Created] (MAPREDUCE-4704) TaskHeartbeatHandler misreports a ping timeout as a task timeout
Date Thu, 04 Oct 2012 14:33:47 GMT
Jason Lowe created MAPREDUCE-4704:

             Summary: TaskHeartbeatHandler misreports a ping timeout as a task timeout
                 Key: MAPREDUCE-4704
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4704
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am, mrv2
    Affects Versions: 0.23.3
            Reporter: Jason Lowe
            Priority: Minor

When a task fails to ping within the hardcoded ping timeout of 5 minutes, TaskHeartbeatHandler
logs a message reporting the wrong timeout value.  It reports a timeout of mapreduce.task.timeout
seconds rather than the 5 minute ping timeout.

This can lead to user confusion if they try increasing mapreduce.task.timeout and see the
log message showing the larger value but the task continues to timeout after only 5 minutes.
