Subject [jira] [Commented] (HBASE-18520) Add jmx value to determine true Master Start time
Date Mon, 07 Aug 2017 18:18:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16116976#comment-16116976
] 

Zach York commented on HBASE-18520:
-----------------------------------

I'm confused about why I would need release manager approval for that? branch-2, branch-1.4,
and branch-1.3 are all the "master" branches for those releases. Whether they are included
in the actual release or not when that branch/tag is created should be up to the release manager.

I don't see any issue with including all fixes that aren't more major features in all the
branches.

> The masterActiveTime is being set before regions are assigned. This patch adds a new
jmx metric to expose the final time when the master has become the active master (All regions
are assigned, etc.).
