ramkrishna.s.vasudevan commented on HBASE-6721: ----------------------------------------------- Ok, so if a region gets splitted then the daughter regions fall in the parents's group? So the group info file will be updated based on this info? Also groups cannot be updated once created right? > 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 > > Attachments: HBASE-6721-DesigDoc.pdf > > > 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.
