You can diagnose Okera installation by:
- Checking if the cluster came up at all.
- Diagnose by looking at /var/log/okera/deployment-manager.log
- If all services came up, check if 7/7 services came up.
- If not, log inspection as mentioned in another faq helps diagnose.
- Check queries are succeeding using client (web ui showing datasets and then preview of sample data).
