Description

1. Examining HADOOP-264 bug I realized that not all rpc server exceptions are actually returned to the client. Particularly, if an exception happens in
org.apache.hadoop.ipc.Server.Connection.run()
for example inside
param.readFields(in);
then it logged but never returned back to the client.
Client simply timeouts in this case, which is not exactly what one would expect.

2. On the way back
org.apache.hadoop.ipc.Client.call()
rpc client always throws a RemoteException, rather than the exception wrapped into this RemoteException.
