----------------------------------
Summary: RegionServer Group based Assignment
Key: HBASE-6721
URL: https://issues.apache.org/jira/browse/HBASE-6721
Project: HBase
Issue Type: New Feature
Reporter: Francis Liu
Assignee: Vandana Ayyalasomayajula
Fix For: 0.96.0
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.
