huxihx opened a new pull request #4913: KAFKA-6814: Refine shown message when
failing to delete groups
URL: https://github.com/apache/kafka/pull/4913
https://issues.apache.org/jira/browse/KAFKA-6814
When deleting a nonexistent group, exception message is as below:
`The group id The group id does not exist was not found` which is very
unfriendly. This patch will fix this misleading message in this case, and also
cover deleting-not-empty-group as well.

tests are expected for any behaviour change and

> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 1.1.0
> Reporter: huxihx
> Assignee: huxihx
> Priority: Minor
>
> Both `GroupNotEmptyException` and `GroupIdNotFoundException` constructors
> accept group id to deliver the exception message. However they can only be
> created with a fixed string "The group id does not exist" or "The group is
> not empty" which leads to a very unfriendly message when user failed to
> delete consumer groups, as below:
> {code:java}
> java.util.concurrent.ExecutionException:
> org.apache.kafka.common.errors.GroupIdNotFoundException: The group id The
> group id does not exist was not found{code}
> group id got failed to be shown in the thrown exception.
