Right now, the Exception handling path is slightly different from the main
path, and would just treat everything as failures, regardless. The
BulkWriterComponent catches exceptions and uses its complete list to mark
everything as failed regardless of what the response is.
The write() method interface does note in the comments that an exception
should be treated as a full batch failure, but it could pretty easily be
modified to catch the exception, mark failures and kick it back up that way. I
left it as-is, because that matches current behavior exactly. At that point,
I'd want to do the same thing for all the implementations (hbase, etc.)
