Suresh Srinivas commented on HDFS-654:
--------------------------------------
> FSNameSystem.checkFsObjectLimit()
The count changes when the destination is removed.
{{FSDirectory.removeChild(dstInode)}} and
{{FSNamesystem.removePathAndBlocks()}} decrements the total INode count and the
number of blocks. Also the lease to the removed destination is also removed.
> HDFS needs to support new rename introduced for FileContext
