Re: Task attempt failed after TaskAttemptListenerImpl ping
Harsh J 2013-05-24, 05:24
Assuming you mean "failed" there instead of "filed".

In MR, a ping message is sent over the TaskUmbilicalProtocol from the
Task container to the MR AM. A ping is only sent as an alternative, to
check self, if there's no progress to report from the task. No
progress to report for a long time generally means the task has
stopped doing work/isn't updating its status/is stuck.
