--------------------------------------
This work can assign to me. Now I am thinking do the work.
My basic idea is every tablet server leaders' number : replicas' number should
be 1:3.
If needed , I can write a doc to describe my detail thought.
Adding another thread in master do the work, only leader can run the leader
rebalance.
The work should based on replica rebalances work enabled.
> Balance tablet leaders across TServers

> URL: https://issues.apache.org/jira/browse/KUDU-3061
> Project: Kudu
> Issue Type: New Feature
> Components: api, tablet
> Affects Versions: 1.11.1
> Reporter: Adam Voga
> Priority: Major
> Labels: performance, roadmap-candidate, scalability
>
> The number of leader tablets per tablet server can become imbalanced over
> time, putting additional pressure on a few nodes.
> A CLI tool or an extension to the existing balancer should be added to take
> care of this.
> Currently the only option is running leader_step_down manually.
