stack commented on HBASE-6721:
------------------------------
Late to the game... but maybe below is of some help:
Design doc should have author, date, and reference to this issue.
Something is incomplete around here in the doc ... "configured to not use the
region server grouping features,"
Should explain why table has such an odd-looking name “0group0”
When you refer to servers in the shell, should you use the full servername
rather than just host and port? e.g:
group_move_servers 'dest',['server1:port','server2:port']
Doc. looks good Francis.

> 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.
