> 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 '%'.
