---------------------------------
Reviewer: Neha Narkhede
> Improve controller and broker message handling.
> -----------------------------------------------
>
> Key: KAFKA-1701
> URL: https://issues.apache.org/jira/browse/KAFKA-1701
> Project: Kafka
> Issue Type: Improvement
> Reporter: Jiangjie Qin
>
> This ticket is a memo for future controller refactoring.
> It is related to KAFKA-1547. Ideally, the broker should only follow
> instruction from controller but not handle it smartly. For KAFKA-1547, the
> controller should filter out the partitions whose leader is not up yet before
> send LeaderAndIsrRequest to broker.
> The idea is controller should handle all the edge cases instead of letting
> broker do it.
