Andrii Biletskyi commented on KAFKA-1367:
-----------------------------------------
[~jjkoshy] Yes, it appears that topic commands don't require ISR information so
it was proposed to remove it at all from the TopicMetadataRequest. There was an
idea to create some sort of BrokerMetadataRequest which will include correct
topic metadata but since it's not related to KIP-4 directly it won't be a part
of it. So everyone is welcome to create a separate KIP for it. Atleast to this
conclusion we came last time.
> Broker topic metadata not kept in sync with ZooKeeper

> When a broker is restarted, the topic metadata responses from the brokers
> will be incorrect (different from ZooKeeper) until a preferred replica leader
> election.
> In the metadata, it looks like leaders are correctly removed from the ISR
> when a broker disappears, but followers are not. Then, when a broker
> reappears, the ISR is never updated.
> I used a variation of the Vagrant setup created by Joe Stein to reproduce
> this with latest from the 0.8.1 branch:
