Description

Since the Protobufification of Hadoop, the log messages on IPC exceptions on the server side now read like:

12/04/09 16:04:06 INFO ipc.Server: IPC Server handler 9 on 8021, call org.apache.hadoop.ipc.ProtobufRpcEngine$RpcRequestWritable@7087e9bf from 127.0.0.1:47989: error: org.apache.hadoop.ipc.StandbyException: Operation category READ is not supported in state standby

The call should instead stringify the method name and the request protobuf (perhaps abbreviated if it is longer than a few hundred chars)
