--------------------------------------

Pushing it out from 2.9.0 due to lack of recent activity. Feel free to revert if required.

> It would be great to have in the info log corresponding to block report processing, printing
information on how many block reports have been processed. This can be useful to debug when
namenode is unresponsive especially during startup time to understand if datanodes are sending
block reports multiple times.
