> In multi-tenant deployments of HBase, it is likely that a RegionServer will be serving out regions from a number of different tables owned by various client applications. Being able to group a subset of running RegionServers and assign specific tables to it, provides a client application a level of isolation and resource allocation.
> The proposal essentially is to have an AssignmentManager which is aware of RegionServer groups and assigns tables to region servers based on groupings. Load balancing will occur on a per group basis as well. 
> This is essentially a simplification of the approach taken in HBASE-4120. See attached document.
