      Description

      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
