Resolution: Won't Do
> Validate the replicas for partition reassignments triggered through the

> Key: KAFKA-9094
> URL: https://issues.apache.org/jira/browse/KAFKA-9094

> Issue Type: Improvement

> Priority: Minor

> As was mentioned by [~jsancio] in
> [https://github.com/apache/kafka/pull/7574#discussion_r337621762] , it would
> make sense to apply the same replica validation we apply to the KIP-455
> reassignments API.
> Namely, validate that the replicas:
> * are not empty (e.g [])
> * are not negative negative (e.g [1,2,-1])
> * are not brokers that are not part of the cluster or otherwise unhealthy
> (e.g not in /brokers zNode)
> The last liveness validation is subject to comments. We are re-evaluating
> whether we want to enforce it for the API
