The message that youa re getting is not an "Error" is it a "Warning" instead.
You can avoid it by telling ambari to not to perform the DB consistency check upon the ambari server restart as following:
# ambari-server start --skip-database-check
The Warning message indicates that your database has few inconsistency (although it will work with skip-database-check as it is not error) but that needs to be fixed in future. That will require a Ambari DB dump analysis and to manually fix those by running some SQL queries.

If startet with that workaround there is warning:
Ambari Server is starting with the database consistency check skipped. Do not make any changes to your cluster topology or perform a cluster upgrade until you correct the database consistency issues. See "/var/log/ambari-server/ambari-server-check-database.log" for more details on the consistency issues.
But that "cluster upgrade" is exactly what i did. (after ignoring the Warning)
Additional after that an error message comes, but the ambari WebGUI is up.
Waiting for server start............................................................ERROR: Exiting with exit code 1. REASON: Server not yet listening on http port 8080 after 50 seconds. Exiting.
Any advice on how to repair the db?

Consistency checks were added to Ambari because there were few if any referential integrity checks in the ambari DB repository initially and unexpected situations do occur from time-to-time resulting in orphaned records in tables. By adding checks, the aim is to catch issues sooner rather than later. Some DB consistency check violations are not show-stoppers. You've probably had them for a while and you can live with them a while longer. You could try and unpick the orphaned records, backup and delete them. But you are fine continuing with them.
You can find these orphans using the following query in your mysql ambari database:
mysql> select config_id, version_tag, version, type_name from clusterconfig c where not exists (select 1 from serviceconfigmapping s where s.config_id = c.config_id);
You could take a backup of these and delete them.
As mentioned below there is a patch available that will sort his for you in Ambari 2.5.2.
You could wait for that.

This is a bug and there is patch available. It will be fixed in Ambari 2.5.2.

Some of your Mysql database engine are MYISAM, to resolve that do the following
# mysql -u root -ptest1234
check the databases, choose your ambari database in my case ambari
mysql> show databases; mysql> use ambari;
Check the tables that are MYISAM
mysql> SELECT TABLE_NAME,ENGINE FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'ambari';
Run the below command for every single table that was marked as MyISAM replace xxx with table name from the above output
ALTER TABLE xxx ENGINE = InnoDB;
All your tables should now be using InnoDB engine
Now your database should be clean you can restart your Ambari server the DB inconsistency should be resolved
Hope that helps please revert

Thanks @Geoffrey Shelton Okot for writing.
while migrating the mysql I have already changed it to InnoDB. You can see it here.
still the problem is there.
|serviceconfigmapping | InnoDB |
| servicedesiredstate | InnoDB |
| setting | InnoDB | |
stack | InnoDB |
| stage | InnoDB |

clusterconfigmapping from ambari db is missing which was there before I upgrade hdp2.6
Created 06-02-2018 05:54 AM
Please find below the procedure to clean you orphaned Ambari configs
Create the temporary table to hold the orphaned configs
CREATE TEMPORARY TABLE IF NOT EXISTS orphaned_configs AS (SELECT cc.config_id, cc.type_name, cc.version_tag FROM clusterconfig cc, clusterconfigmapping ccm WHERE cc.config_id NOT IN (SELECT scm.config_id FROM serviceconfigmapping scm) AND cc.type_name != 'cluster-env' AND cc.type_name = ccm.type_name AND cc.version_tag = ccm.version_tag);
Delete the orphaned tables
DELETE FROM clusterconfigmapping WHERE EXISTS (SELECT 1 FROM orphaned_configs WHERE clusterconfigmapping.type_name = orphaned_configs.type_name AND clusterconfigmapping.version_tag = orphaned_configs.version_tag);
Delete the orphaned configs
DELETE FROM clusterconfig WHERE clusterconfig.config_id IN (SELECT config_id FROM orphaned_configs);
Validate that the orphaned configs are gone
SELECT * FROM orphaned_configs;
Drop the temporary table
DROP TABLE orphaned_configs;
Now you Ambari databases should be clean and all your configs properly mapped to the serviceconfigmapping table.
Please let me know if that worked well for you !!

Do you still have the backup/dump of your pre-upgrade Ambari MySQL?
Did you encounter any problems during the upgrade and simply ignored it? The desired output should have been like below
INFO: Upgrading database schema INFO: Return code from schema upgrade command, retcode = 0 INFO: Schema upgrade completed Adjusting ambari-server permissions and ownership... Ambari Server 'upgrade' completed successfully.
