Thanks [~xiaobingo] for the update. One more issue found on the rendered
webhdfs.html (changes in webhdfs.md)

-------------------------------------
WebHDFS supports an optional, configurable retry policy for resilient copy of
large files that could timeout, or copy file between HA clusters that could
