Ashish Singhi commented on HBASE-15291:
---------------------------------------

I have verified this manually. 

Before patch, after running LoadIncrementalHFiles tool, if we then run below 
command, we will see a increase in the DistributedFileSystem reference. The 
patch fixes this issue.

jmap -histo:live <RS_PID> | grep DistributedFileSystem
