Ted Yu resolved HBASE-3799. --------------------------- Resolution: Later > Provide more accurate check for super underloaded region server in load > balancer > -------------------------------------------------------------------------------- > > Key: HBASE-3799 > URL: https://issues.apache.org/jira/browse/HBASE-3799 > Project: HBase > Issue Type: Bug > Components: mapreduce > Affects Versions: 0.90.2 > Reporter: Ted Yu > Assignee: Ted Yu > Attachments: 3799.patch > > > HBASE-3609 used simple check for region server which recently joined the > cluster so that both young and old regions from other region servers are > assigned to it. > The check was too strict. > 1 or more region may be assigned to this server before load balancer performs > rebalancing. > The next time balancer runs, it wouldn't treat this server as seriously > underloaded correctly and assign a lot of young regions to it. > We can use threshold over the number of regions to avoid such issue. -- This message is automatically generated by JIRA.
