[jira] [Created] (HBASE-21521) Expose master startup status via JMX and web UI

Andrew Purtell created HBASE-21521:
--------------------------------------

             Summary: Expose master startup status via JMX and web UI
                 Key: HBASE-21521
                 URL: https://issues.apache.org/jira/browse/HBASE-21521
             Project: HBase
          Issue Type: Improvement
          Components: master, UI
            Reporter: Andrew Purtell


Add an internal API to the master for tracking startup progress. Expose this information via JMX.

Modify the master to bring the web UI up sooner. Will require tweaks to various views to prevent attempts to retrieve state before the master fully up (or else expect NPEs). Currently, before the master has fully initialized an attempt to use the web UI will return a 500 error code and display an error page.

Finally, update the web UI to display startup progress, like HDFS-4249. (Example: [^HDFS-4249-2.png)]

Filing this for branch-1. Need to check what if anything is available or improved in branch-2 and master.
