Charles Lamb updated HDFS-7579:
-------------------------------
Attachment: HDFS-7579.000.patch
The attached patch modifies BPServiceActor so that even if one or more of the
block report rpcs fails, a LOG.info message will still be displayed. This will
help diagnose cases where the RPC throws an exception. This patch also adds a
toString() to ServerCommand so that the LOG.info message displays something
reasonable for the commands that it received back rather than just
Object.toString().
