[jira] [Created] (MAPREDUCE-6816) Progress bars in Web UI always at 100%

Shen Yinjie created MAPREDUCE-6816:
--------------------------------------

             Summary: Progress bars in Web UI always at 100% 
                 Key: MAPREDUCE-6816
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6816
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: webapps
    Affects Versions: 3.0.0-alpha2
            Reporter: Shen Yinjie
            Assignee: Shen Yinjie


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 '%'.
