Robert Joseph Evans commented on MAPREDUCE-4252:
------------------------------------------------

The patch looks good to me.  I have read through the code and looked at the state transition graphs and I don't see any issues with it.  +1

On a side note I would like to get this into branch-0.23 as well, patch applies with no problems there.

> bq. I ran a teragen with 1000 map tasks. Many task attempts failed, but after 999 of the tasks had completed, the job is now sitting forever with 1 task "pending".
