Hello Team, Sorry for late response, I have created external metastore using MySql and make them up. Now my cluster is looking good. Thanks Team for your efforts . Best Regards,Vinod

In such a case, you should attach the logs because that's the only source we can use to investigate and get tips of maybe what happened.

How long have you cluster been running before going down? Did you ever purge the CMS database? On large deployments, it's a good strategy to put the monitor roles on their own hosts and isolation.

Now that you have deleted the CMS hence lost the data therein you can safely create a new backend database and point the new config to that instance.

DB's to recreate

Reports Manager
Activity Monitor
