Description

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.
