Devaraj Das commented on HADOOP-3462:
-------------------------------------
Christian, are you seeing the reduce task failures being caused by merge
failures. Looking at the code, it didn't seem that reduce task fails when a
fetch fails due to bad disk.
> reduce task failures during shuffling should not count against number of
> retry attempts
