As Neha said, the 1st copy of a partition is the preferred replica and we
try to spread them evenly across the brokers. When a broker is restarted,
we don't automatically move the leader back to the preferred replica
though. You will have to run a command line
tool PreferredReplicaLeaderElectionCommand to balance the leaders again.

Also, I recommend that you try the latest code in 0.8. A bunch of issues
have been fixes since Jan. You will have to wipe out all your ZK and Kafka
data first though.
