Arpit Agarwal updated HDFS-5390:
--------------------------------
Attachment: h5390.03.patch
Fix BPServiceActor to track incremental BR state per storage.
Send one incremental BR for each storage to the Namenode. Ideally we'd like to
send a single message with incremental BR for all storages but it cannot be
done without an incompatible change to the protocol.
> Incremental block reports should be sent per storage directory

> 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.
