I have the same experience when install openstack . when I install sync DB and perform su -s /bin/sh -c "keystone-manage db_sync". Once you performance those command , User –uroot –p root XXX(XXX indicate your DB password, login DB, then perform use keystone ; show tables.

If you can see the following , show tables; +------------------------+ | Tables_in_keystone | +------------------------+ | access_token | | assignment | | config_register | | consumer | | credential | | domain | | endpoint | | endpoint_group | | federation_protocol | | group | | id_mapping | | identity_provider | | idp_remote_ids | | mapping | | migrate_version | | policy | | policy_association | | project | | project_endpoint | | project_endpoint_group | | region | | request_token | | revocation_event | | role | | sensitive_config | | service | | service_provider | | token | | trust | | trust_role | | user | | user_group_membership | | whitelisted_config | +------------------------+ 33 rows in set (0.00 sec)

That is saying, you can ignore the error.

I have the same error when trying to populate the compute database. I can't even start nova-compute service. So, can't continue with the setup...
