> Incremental block reports should be sent per storage directory since the NameNode now
expects all block reports to be sent per storage. Currently the Datanode tracks pending incremental
block reports for all storages in a single queue.
> This is a continuation of the work started by HDFS-5134 and HDFS-4988 to split block
processing per storage directory.
