Steve Loughran commented on HADOOP-1561:
----------------------------------------
what level should it log at? I'd hate for server-side logs to overflow because
clients are playing games with the server; we'd need to filter out anything a
client can trigger
> RPC server should log exceptions that are not sent to client.

> RPC server logs and sends the exceptions that occur inside the call. But if
> there is an exception during construction of objects, the exception is not
> logged. Clients just see EOF because server closes the connection.
> I got bitten by this since couple of my objects did not have default
> constructors (and same case if readFields() throws an NPE). This is a silly
> mistake on my part but I think it is easy to make the mistake but hard to see
> where the problem is.
> Server can still close the connection but should log it at the server.
