Jian He commented on YARN-2136:
-------------------------------

[~varun_saxena], thanks for updating!  looks good overall,
one minor comment: we may break out of the while loop if it's at FENCED state.
{code}
          if(!isFencedState()) { 
            doMultiWithRetries(emptyOpList);
          }
{code}
