------------------------------------
[~zjushch]
We have the 0.94 running in our cluster for a while now.
I've uploaded the trunk patch on review board:

Since we have all the tables' group info, could we remove
GroupInfo.TABLEDESC_PROP_GROUP?
{quote}
This is needed so we can create and assign a table to a group as part of a
create table request.
{quote}
Could we only use hbase table to storage group information?
{quote}
Yes this is already done in the current implementation.
{quote}
When we update the group information, why not update the memory the first? Then
we need't roll back if persistence failed
{quote}
Can you call out which section in GroupInfoManager you're referring to?

> 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.
