> There are two things this jira tries to address:
> 1. The locality picker in the stochastic balancer does not pick regions with
> least locality as candidates for swap/move. So when any user configures
> locality cost in the configs, the balancer does not always seems to move
> regions with bad locality.
> 2. When a cluster has equal number of loaded regions, it always picks the
> first one. It should pick a random region on one of the equally loaded
> servers. This improves a chance of finding a good candidate, when load picker
> is invoked several times.
