Brahma Reddy Battula commented on HDFS-11896:
---------------------------------------------

[~shv] thanks a lot for review and debugging this..

bq.For branch-2.7 combination of these two bugs makes nonDfsUsed counted twice 
on re-registration.
Uploaded patch is combination only.
and for trunk also patch is available with just reseting the non-dfs used.

> Non-dfsUsed will be doubled on dead node re-registration in branch-2.7.
