Gwen Shapira commented on KAFKA-2100:
-------------------------------------

We have KAFKA-1929 for re-using the Errors package in the server side.

> Client Error doesn't preserve or display original server error code when it 
> is an unknown code

>
> When the java client receives an unfamiliar error code, it translates it into 
> UNKNOWN(-1, new UnknownServerException("The server experienced an unexpected 
> error when processing the request"))
> This completely loses the original code, which makes troubleshooting from the 
> client impossible. 
> Will be better to preserve the original code and write it to the log when 
> logging the error.
