Sharad Agarwal commented on MAPREDUCE-2708:
-------------------------------------------
bq. and the AM restarted with 83% map and 0% reduce
great! it worked.
btw Vinod, with recovery module unable to parse the history file (due to hdfs
bug), it should fall back to restarting the job. just curious, did you notice
that?
