Date Fri, 04 Aug 2017 17:00:05 GMT
Zach York created HBASE-18520:
---------------------------------

             Summary: Add jmx value to determine true Master Start time
                 Key: HBASE-18520
                 URL: https://issues.apache.org/jira/browse/HBASE-18520
             Project: HBase
          Issue Type: Bug
          Components: metrics
            Reporter: Zach York
            Assignee: Zach York
            Priority: Minor


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.).
