Vinod K V commented on HADOOP-5280:
-----------------------------------
The original circumstances under which this bug was revealed was HADOOP-5285.
With the above patch, and without patch for HADOOP-5285, the symptom of stuck
reducers waiting for output from already failed tasks doesn't seem to be
visible any more.
The patch uploaded prevents tasks from wrongly going from FAILED state to any
of UNASSIGNED, RUNNING, COMMI_PENDING or SUCCEEDED and looks fine.
`ant test` and `ant test-patch` passed successfully on my local machine. +1
overall.
> When expiring a lost launched task, JT doesn't remove the attempt from the
> taskidToTIPMap.
