> The master currently only does region assignments at startup or when there
> are splits or dead regionservers. This means that if you join a new
> regionserver to the cluster after startup, it does not get assigned a fair
> share of the already-served regions as you would expect. It only gets a share
> of new regions being served.
> The master should periodically check the balance of regions, based on
> whatever assignment function, instead of in reaction to the above listed
> events.
