Mahadev konar commented on MAPREDUCE-2708:
------------------------------------------
I tried the latest patch out on 0.23, it worked for me. I killed a
randomwriter job at 83% map and 0% reduce and the AM restarted with 83% map and
0% reduce. Nicholas tells me that the error above could just be a bug in trunk
due to HDFS-2181 or such.
Vinod, are you using trunk or 0.23? If trunk, can you try it out with 0.23?
