> 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.
