Hi, Friends, I used Openstack-Juno heat, keystone and Mitaka sahara. Sahara is installed in docker container using host network. When sahara wants to call heat to create a hadoop cluster, the below error is happened. Could you help to check this issue? I guess, the heat couldn't create user in keystone. The attachment is the conf file and log file. Please reference them. Thanks for your help in advance. 2016-05-31 11:22:45.625 41759 INFO urllib3.connectionpool [-] Starting new HTTP connection (1): 10.252.100.4 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource Traceback (most recent call last): 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/engine/resource.py", line 435, in _action_recorder 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource yield 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/engine/resource.py", line 505, in _do_action 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource yield self.action_handler_task(action, args=handler_args) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/engine/scheduler.py", line 286, in wrapper 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource step = next(subtask) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/engine/resource.py", line 476, in action_handler_task 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource handler_data = handler(*args) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/engine/resources/wait_condition.py", line 143, in handle_create 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource token = self._user_token() 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/engine/stack_user.py", line 75, in _user_token 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource project_id=project_id, password=password) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/heat/common/heat_keystoneclient.py", line 410, in stack_domain_user_token 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource authenticated=False) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/keystoneclient/session.py", line 430, in post 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource return self.request(url, 'POST', **kwargs) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/keystoneclient/utils.py", line 318, in inner 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource return func(*args, **kwargs) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource File "/usr/lib/python2.6/site-packages/keystoneclient/session.py", line 346, in request 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource raise exceptions.from_response(resp, method, url) 2016-05-31 11:22:45.663 41759 TRACE heat.engine.resource Unauthorized: Could not find user: haddp45018380-test-master-ajdlwfudliu2-0-hnnojqmbzkbr-test-master-wc-handle-dp4cqhkmtykr (Disable debug mode to suppress these details.)
