Subject [jira] [Commented] (HBASE-18051) balance_rsgroup still run when the Load Balancer is not enabled.
Date Tue, 16 May 2017 02:44:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16011658#comment-16011658

Guangxu Cheng commented on HBASE-18051:
---------------------------------------

bq.See if you can utilize existing method(s) and not add isBalancerOn() to MasterServices

yep, isBalancerEnabled () calls the method isBalancerOn() in HMaster to get the state of the
load balancer.
In RSGroupAdminServer, the type of master is MasterServices, but isBalancerOn() is not defined
in MasterServices, so I add isBalancerOn() to MasterServices.
Can I use (HMaster) master).isBalancerOn() instead of adding isBalancerOn() to MasterServices?

> When the Load Balancer is not enabled, the command "balancer" will not be executed ,
but the command "balance_rsgroup" can still run, which is not reasonable.So we need to fix
it
