I finally engaged Cloudera support. After checking the security value with the following command : /var/lib/ambari-server/resources/scripts/configs.py -l <ambari host fqdn> -t <port> -u admin -p <password> -n <cluster_name> -a get -c cluster-env | grep -i security_enabled, I was asked to disable the security_enabled : /var/lib/ambari-server/resources/scripts/configs.py -l <ambari host fqdn> -t <port> -u admin -p <password> -n <cluster_name> -a set -c cluster-env -k security_enabled -v false Then i was able to start ranger again Still have problem with infa_solr. I will engage support for that

After restarting all the services trough ambari, only two services don't start and are facing the same error : ranger and infrasolr /usr/lib/python2.6/site-packages/resource_management/libraries/script/config_dictionary.py", line 73, in __getattr__
raise Fail("Configuration parameter '" + self.name + "' was not found in configurations dictionary!")
resource_management.core.exceptions.Fail: Configuration parameter 'kerberos-env' was not found in configurations dictionary! Any idea ? Thanks
