Description

With the introduction of `kudu cluster rebalance` CLI tool it's possible to balance the distribution of tablet replicas in a Kudu cluster. However, that tool should be run manually or via an external scheduler (e.g. cron).

It would be nice if Kudu would track and correct imbalances of replica distribution automatically.
