------------------------------------

[~markrmiller@gmail.com] is this worth back porting to 5.5.1? This is a clean cherry-pick
but I'll let you decide on this one.

> After a Merge Indexes, the input directories on HDFS do not get closed (only released
by the CachingDirectoryFactory). This causes the HDFSLocalityReporter to continue monitoring
the input directories even after they are cleaned up/deleted. This results in a large volume
of logged warnings on the Solr node.
