Devaraj Das commented on HADOOP-6029:
-------------------------------------
Although the fix looks right from the testcase point of view, but IMO we should
still investigate why and where this 83 bytes from local disk are read (as
logged in Nicholas's testReduceFromMem failure)
> TestReduceFetch failed.
