Attaching screenshots.
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
