Guozhang Wang commented on KAFKA-2100:
--------------------------------------
I like option #2 as well, I think it is sufficient to bring user's attention
with the preserved original error code.
Regarding the inconsistency usage, it is mainly because they are written by two
people (namely me and Jay :P) who did not really sync-up on the usage style. I
do not have a strong preference either way, but Sender's way may be less
characters?

> 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.
