Yes, it's expected. The rebalancing tool does not balance leadership. In
fact, it tries to avoid relocating leader replicas because the tool wants
to minimize the disturbance to the cluster. It will relocate leader
replicas if it has to, but it won't make any attempt to balance them.

You can use 'kudu tablet leader_step_down' to force the leader replica of a
tablet to step down. A new leader will be elected after the election
timeout passes. It's not guaranteed that the old leader won't be reelected.
