Francis Liu commented on HBASE-6721:
------------------------------------
Latest patch attached. The patch makes the implementation cp-based.
To avoid confusion I've created a new RB entry:
https://reviews.apache.org/r/38224/
[~apurtell] The new patch is based off of current master. Should we just
replace the current branch with a new branch to go with the new patch? Also was
wondering since this is now cp-based. Do we still need a branch?
[~eclark] I believe I've addressed most of your concerns. The only thing I
missed was "Load meta's hri from disk on move" can you elaborate more one what
needs to be done on RB?

> 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.
