stack commented on HBASE-10873: ------------------------------- bq. Probably it's better to do some consolidation and use just the configuration in this patch? It would make this patch indispensible (smile). > Control number of regions assigned to backup masters > ---------------------------------------------------- > > Key: HBASE-10873 > URL: https://issues.apache.org/jira/browse/HBASE-10873 > Project: HBase > Issue Type: Improvement > Components: Balancer > Reporter: Jimmy Xiang > Assignee: Jimmy Xiang > Fix For: 0.99.0 > > Attachments: hbase-10873.patch, hbase-10873_v2.patch > > > By default, a backup master is treated just like another regionserver. So it > can host as many regions as other regionserver does. When the backup master > becomes the active one, region balancer needs to move those user regions on > this master to other region servers. To minimize the impact, it's better not > to assign too many regions on backup masters. It may not be good to leave the > backup masters idle and not host any region either. > We should make this adjustable so that users can control how many regions to > assign to each backup master. -- This message was sent by Atlassian JIRA (v6.2#6252)
