> 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 '%'.
