Thanks @Hexiaoqiao for merging!
Checked out the commit from trunk branch and saw "Contributed by" was changed from "Ravindra Dingankar [rdingankar@linkedin.com](mailto:rdingankar@linkedin.com)." to myself, which was unexpected. I intentionally put "Contributed by Rav" in the commit message. I should have communicated this to @Hexiaoqiao before he merges the PR.
The change was originally created by Rav and I just helped contribute it back to open-source while he was on a vacation.

> 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.
