Forward port some changes from 0.98 feature branch, 2. Address CP backward compatibility support, 3. Address removal of GroupAdmin and GroupAdminClient and moving the apis to Admin. Let me know if you'd like me to break these up into separate patches. Didn't do that as I thought it'd be more complicated. > 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: Francis Liu > Labels: hbase-6721 > Attachments: 6721-master-webUI.patch, HBASE-6721 GroupBasedLoadBalancer Sequence Diagram.xml, HBASE-6721-DesigDoc.pdf, HBASE-6721-DesigDoc.pdf, HBASE-6721-DesigDoc.pdf, HBASE-6721-DesigDoc.pdf, HBASE-6721_0.98_2.patch, HBASE-6721_10.patch, HBASE-6721_11.patch, HBASE-6721_8.patch, HBASE-6721_9.patch, HBASE-6721_9.patch, HBASE-6721_94.patch, HBASE-6721_94.patch, HBASE-6721_94_2.patch, HBASE-6721_94_3.patch, HBASE-6721_94_3.patch, HBASE-6721_94_4.patch, HBASE-6721_94_5.patch, HBASE-6721_94_6.patch, HBASE-6721_94_7.patch, HBASE-6721_98_1.patch, HBASE-6721_98_2.patch, HBASE-6721_hbase-6721_addendum.patch, HBASE-6721_trunk.patch, HBASE-6721_trunk.patch, HBASE-6721_trunk.patch, HBASE-6721_trunk1.patch, HBASE-6721_trunk2.patch, balanceCluster Sequence Diagram.svg, immediateAssignments Sequence Diagram.svg, randomAssignment Sequence Diagram.svg, retainAssignment Sequence Diagram.svg, roundRobinAssignment Sequence Diagram.svg > > > 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.
