Description

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 StringUtils.format() contains '%', while in *Block.java use join() add an extra '%'.
