Lars Hofhansl commented on HBASE-6721:
--------------------------------------

Can this also colocate regions of different tables, maybe based on a key prefix?
In our case we'd tenants share tables, and each row key would be a prefixed by 
a tenant id.

> 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.
