Vinod Kumar Vavilapalli updated MAPREDUCE-5476:
-----------------------------------------------
Status: Open (was: Patch Available)
The approach sounds fine to me. This looks like a clear follow up from
MAPREDUCE-4819 that we never pursued.
OTOH, though I didn't always feel comforable with the FINISHING state, things
like these prove its practical wins :)
Re the patch:
- The java comments needs to be slightly improved to reflect what we are
really doing
- Test:
-- Rename cleanupStagingDir to stagingDirCleanedUp.
-- Not related to your patch but can you also modify the test a little to
make sure the JobHistoryEventHandler is the first thing to shut-down?
> Job can fail when RM restarts after staging dir is cleaned but before MR
> successfully unregister with RM
