Arpit Agarwal commented on HDFS-7579:
-------------------------------------

You are right - it cannot be null. I confused it with cmd.

+1 for the .001 patch. I will hold off committing until the evening just in case Chris has
comments.

Thanks!

> During block reporting, if the block report RPC fails, for example because it exceeded
the max rpc len, we should still produce some sort of LOG.info output to help with debugging.
