On Ambari Server start, Ambari runs a database consistency check looking for issues. If any issues are found, the Ambari Server start will abort and display the following message: DB configs consistency check failed.

Ambari writes more details about database consistency check results to the /var/log/ambari-server/ambari-server-check database.log file.

You can force the Ambari Server to start by skipping this check with the following option: ambari-server start --skip-database-check

If you have database issues, by choosing to skip this check, do not make any changes to your cluster topology or perform a cluster upgrade until you correct the database consistency issues. Contact Acceldata Support and provide the ambari server-check-database.log output for assistance.
