Jun Rao commented on KAFKA-1367: -------------------------------- Yes, perhaps some kind of more general locality could be useful. That can be done in a separate jira. Here, we just want to figure out whether it's useful to maintain ISR in TMR. [~jjkoshy], another issue without ISR is that initially a client will have no idea which replica is in sync and can only guess. > Broker topic metadata not kept in sync with ZooKeeper > ----------------------------------------------------- > > Key: KAFKA-1367 > URL: https://issues.apache.org/jira/browse/KAFKA-1367 > Project: Kafka > Issue Type: Bug > Affects Versions: 0.8.0, 0.8.1 > Reporter: Ryan Berdeen > Assignee: Ashish K Singh > Labels: newbie++ > Fix For: 0.8.3 > > Attachments: KAFKA-1367.txt > > > 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: > https://github.com/also/kafka/commit/dba36a503a5e22ea039df0f9852560b4fb1e067c -- This message was sent by Atlassian JIRA (v6.3.4#6332)
