   Sounds good. I wasn't suggesting to revert/overwrite this commit.  Just 
wanted to put a note here to make it clear it was contributed by rav instead of 
me. Rav was aware that I was doing this on his behalf.

> HDFS-16917 added a LOG.warn when passed duration is 0. The unit for duration 
> is millis, and its very possible for a read to take less than a millisecond 
> when considering local TCP connection. We are seeing this spam multiple times 
> per millisecond. There's another report on the PR for HDFS-16917.
> Please downgrade to debug or remove the log
