Ted Yu commented on HBASE-12559: -------------------------------- Synchronization is achieved by taking lock on HMaster.balancer field. Balancer chore respects this locking. > Provide LoadBalancer with online configuration capability > --------------------------------------------------------- > > Key: HBASE-12559 > URL: https://issues.apache.org/jira/browse/HBASE-12559 > Project: HBase > Issue Type: Improvement > Reporter: Ted Yu > Assignee: Ted Yu > Fix For: 2.0.0 > > Attachments: 12559-v1.txt, 12559-v2.txt, 12559-v3.txt, 12559-v4.txt > > > StochasticLoadBalancer has many knobs which user can adjust. > It would increase productivity by allowing StochasticLoadBalancer to accept > online configuration changes. > LoadBalancer already implements setConf(Configuration) method which reloads > relevant configuration parameters. > We need to add updateMasterConfiguration() method to Admin which invokes the > setConf() method. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
