["Jimmy Xiang (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-10923?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jimmy Xiang updated HBASE-10923:
--------------------------------
    Release Note: This patch introduced a new configuration "hbase.balancer.tablesOnMaster" to control what tables' regions should be put on the master by a load balancer. By default, we will put regions of table acl, namespace, and meta on master, i.e. the default configuration is the same as "hbase:acl,hbase:namespace,hbase:meta". To put no region on the master, you need to set "hbase.balancer.tablesOnMaster" to "none" instead of an empty string(the default will be used if it is empty).

> There is a concern on placing meta regions on the master, as in the comments of HBASE-10569. I was thinking we should have a configuration for a load balancer to decide where to put it.  Adjusting this configuration we can control whether to put the meta on master, or other region server.
