Ayush Saxena commented on HDFS-15816:
-------------------------------------

Thanx [~hadoop_yangyun] for the patch, the intention seems good, but is there 
any better way rather than checking for the exception message? I have little 
hard feelings about it, Will just comparing the oldExcluded and the Excluded 
set size be of some relief?
