Hey Brahma, 

Thanks for reporting the issue.

I remember, I have fixed this issue log back.
Looks like, this has been reverted back as part of HA brannch merge.

Fixed as part of https://issues.apache.org/jira/browse/HDFS-2768.
Explained the reason for this issue in above mentioned issue.


Thanks
Uma
