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`))
{noformat}
To get around this, he 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.
