Review request for Ambari, Andrew Onischuk and Sid Wagle.
Bugs: AMBARI-22544
https://issues.apache.org/jira/browse/AMBARI-22544
Repository: ambari
Description
-------
When upgrading from Ambari 2.5.2 to Ambari 2.6.0, we hit this error preventing
from completing the ambari-server upgrade.
```
20 Nov 2017 11:39:08,115 ERROR [main] SchemaUpgradeHelper:202 - Upgrade failed.
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException:
Cannot delete or update a parent row: a foreign key constraint fails
(`ambari_01`.`clusters`, CONSTRAINT `FK_clusters_upgrade_id` FOREIGN KEY
(`upgrade_id`) REFERENCES `upgrade` (`upgrade_id`))
```
To get around this, we had to restore the db backup from 2.5.3 and adjust a
table in mysql with ‘update clusters set upgrade_id = null’ so a record in the
‘upgrades’ table could be removed.
