      Description

      The current logging in the bulk loading RPC call to a RegionServer lacks some info in certain cases. For instance, I recently noticed that it is possible that IOException may be caused during bulk load file transfer (copy) off of another FS and that during the same time the client already times the socket out and thereby does not receive a thrown Exception back remotely (HBase prints a ClosedChannelException for the IPC when it attempts to send the real message, and hence the real cause is lost).

      Improvements around this kind of issue, wherein we could first log the IOException at the RS before sending, and a few other wording improvements are present in my patch.
