> We find that users often run into the default transceiver limits in the DN. Putting aside
the inherent issues with xceiver threads, it would be nice if the "xceiver limit exceeded"
error propagated to the client. Currently, clients simply see an EOFException which is hard
to interpret, and have to go slogging through DN logs to find the underlying issue.
> The data transfer protocol should be extended to either have a special error code for
"not enough xceivers" or should have some error code for generic errors with which a string
can be attached and propagated.
