Aaron Kimball commented on HADOOP-6708:
---------------------------------------

I'm definitely able to help test. I can do some manual testing of large records 
/ performance after there's a patch available.

I wasn't suggesting that we use CountingInputStream in there; I was mostly 
using that as an example of having dual interfaces to retrieve the same value 
-- one as an integer ({{getCount()}}), and the other as a long 
({{getByteCount()}}). This is not my preference; I'd prefer to modify the 
existing methods. But it is an incompatible change, so I figured I'd check 
first.
