2016-04-27 14:22:13,846 - No resources to create. 'create_on_execute' or
'delete_on_execute' wasn't triggered before this 'execute' action.
2016-04-27 14:22:13,846 - Ranger admin not installed
Time 14:21:50 - 14:22:13 was spend just re-running haadmin calls, while we
already figured
This should give ~15s time reduce for Humboldt.
