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.
