   Hi @xinglin @rdingankar , It's not too bad, I will mark rdingankar as 
Contributor at JIRA, and keep git message this time if you don't mind. Because 
revert and checkin code repo again is not very good type when it was not very 
critical issue. What do you think about? Thanks again.

> 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
