Ambari services couldn't be started

Hi, I've upgraded ambari from 2.2 to 2.4. when ambari was started using "ambari-server start" got the error as follows, DB configs consistency check failed. Run "ambari-server start --skip-database-check" to skip. If you use this "--skip-database-check" option, 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. Ambari database consistency check finished In /var/log/ambari-server/ambari-server-check-database.log 2016-12-20 00:33:28,188 INFO - ******************************* Check database started ******************************* 2016-12-20 00:33:47,630 INFO - Checking for configs not mapped to any cluster 2016-12-20 00:33:47,703 INFO - Checking for configs selected more than once 2016-12-20 00:33:47,762 INFO - Checking for hosts without state 2016-12-20 00:33:47,792 INFO - Checking host component states count equals host component desired states count 2016-12-20 00:33:47,826 INFO - Checking services and their configs 2016-12-20 00:34:00,127 ERROR - Required config(s): usersync-properties,ranger-site is(are) not available for service RANGER with service config version 3 in cluster atlas So instead started ambari using "ambari-server start --skip-database-check" and the it worked fine. In /var/log/ambari-server/ambari-server-check-database.log 2016-12-20 00:34:00,131 INFO - ******************************* Check database completed ******************************* 2016-12-20 00:35:26,917 INFO - Checking DB store version 2016-12-20 00:35:30,076 INFO - DB store version is compatible But if logged into the ambari page, "start services" option is in disabled mode. How to start the services..

Thanks!!

The error that you are getting indicates that you have some DB inconsistency. Your issue looks somewhat related to : https://issues.apache.org/jira/browse/AMBARI-18822 Which should be addressed in Ambari 2.5

As a temporary remedy you can try starting the Ambari server as following:

ambari-server start --skip-database-check

DB needs to be checked for the inconsistency fix.
