> hi, there is no limitation about min share of all pools with cluster total
> shares. User can define arbitrary amount of min share for each pool. It has
> such description in <fair scheduler design document>, but no regular code.
> It may critical for slot distribution. One pool can hold all cluster slots to
> meet it's min share that greater than cluster total slots very much.
> If that case has happened, we should scaled down proportionally.
