Greg Harris commented on KAFKA-16420:
-------------------------------------
I can't find a single ticket for "Remove Zookeeper", but I think that is also a
precondition for implementing this change. I found a number of code-paths which
are ZK specific that would make this migration significantly more involved, so
I think it is best that those are removed first.
> Replace utils.Exit with a thread-safe alternative

> Key: KAFKA-16420
> URL: https://issues.apache.org/jira/browse/KAFKA-16420
> Project: Kafka
> Issue Type: Wish
> Components: connect, core, tools
> Reporter: Greg Harris
> Assignee: Greg Harris
> Priority: Minor
>
> The Exit class is not thread-safe, and exposes our tests to race conditions
> and inconsistent execution. It is not possible to make it thread-safe due to
> the static design of the API.
> We should add an alternative to the Exit class, and migrate the existing
> usages to the replacement, before finally removing the legacy Exit.
