Arun C Murthy updated MAPREDUCE-2727:
-------------------------------------
Status: Open (was: Patch Available)
Jeffrey, the patch looks good.
I think this is an appropriate time to remove the copy of SleepJob in mrv2,
it's always bugged me.
Also, will the same patch apply to trunk - can you pls check? Else, I can wait
for the merge and just commit to trunk. Thoughts? Thanks.

> When the count is 0 for mappers or reducers, a divide-by-zero exception is
> thrown. There are existing checks to error out when count < 0, which
> obviously doesn't handle the 0 case. This is causing the MRReliabilityTest
> to fail.
