Benoy Antony commented on MAPREDUCE-4481:
-----------------------------------------
This issue occurs only in those distributions where MAPREDUCE-2415 is applied
as well as MRAsyncDiskService is used to cleanup the volumes during TT startup.
This is not applicable to 1.0 or 1.1 since MRAsyncDiskService is not present in
those.
I don't think , it is applicable to trunk.
