Jun Rao commented on KAFKA-575:
-------------------------------
One way to address this issue is to include the broker info in the leaderAndIsr
request. This way, Partition.makeFollower() doesn't need to read from ZK any
more.

> To follow a new leader, Partition.makeFollower() has to obtain the broker
> info of the new leader. Currently, it reads that info from ZK for every
> affected partition. This increases the time for a leader to truly available.
