[jira] [Commented] (HBASE-26215) The backup master status page should use ActiveMasterManager instead of MasterAddressTracker

    [ https://issues.apache.org/jira/browse/HBASE-26215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17403634#comment-17403634 ] 

Zhuoyue Huang commented on HBASE-26215:
---------------------------------------

Since the backup master status page will remove the MasterAddressTracker, and there is no direct method to obtain ActiveMasterManager (I saw that ActiveMasterManager is a private member of HMaster, and all values in ActiveMasterManager should be returned through HMaster’s public methods). I added some code to make the backup master status page easily retrieve the information it needs.

> On master we already have ActiveMasterManager for tracking active master and backup masters, so we do not need to use MasterAddressTracker.
