> Steps:
> - On HA-enabled cluster go to HBase summary page.
> - Shutdown the current HBase Active Master
> - Verify the hbase quick links menu. You should see "(Active)" for couple of
> hostnames. If not, please refresh and verify.
> - Click the rest api call and verify that two masters have IsActiveMaster
> value as true
