> YARN web UI always shows progress bars at 100% (see screenshot, progress of
> the reduce step is roughly at 40.00%). I opened the HTML source code to check
> (also see screenshot), and it seems the problem is that it uses "%%" ,which
> cannot be recognized. This is due to the output
> of{code}StringUtils.format(){code} contains '%', while in *Block.java use
> {code}join(){code}add an extra '%'.
