> Kafka server returns UnknownServerException for inherited exceptions
> --------------------------------------------------------------------
>
> Key: KAFKA-3189
> URL: https://issues.apache.org/jira/browse/KAFKA-3189
> Project: Kafka
> Issue Type: Bug
> Components: core
> Reporter: Jiangjie Qin
> Assignee: Grant Henke
> Fix For: 0.9.1.0
>
>
> This issue was introduced in KAFKA-2929. The problem is that we are using
> o.a.k.common.protocol.Errors.forException() while all exceptions thrown by
> the broker are still using old scala exception. This cause
> Errors.forException() always return UnknownServerException.
> We should either switch back to Errors.forException() to
> ErrorMapping.codeFor() or migrate all the exceptions to Java exception.
> I prefer the latter option since it seems to be a simple class replacement.
