Masatake Iwasaki commented on HDFS-9726:
----------------------------------------

Thanks for working on this, [~szetszwo]. I think this is good improvement 
making datanode's code clearer.

The patch looks good to me overall. Unit tests passed on my environment. Found 
some nits.

* {{IncrementalBlockReportManager#addRDBI}} should be VisibleForTesting and 
{{IncrementalBlockReportManager#sendImmediately}} is not.
* {{notifyNamenodeBlock}}: I felt the meanings of {{send}} and {{now}} are not 
clear from the variable name. How about {{immediate}} and {{notify}} 
respectively?
