Thanks all for the help. I get help from IRC, and now I have solved my issues:
1. The reason after I update horizon and the "Data Processing" panel do not work is because I missed a step for horizon to work. The correct step to update horizon is: a. git pull origin master (update horizon code) b. python manage.py collectstatic c. python manage.py compress d. sudo service apache2 restart 2. I can't open "job_executions" page is due to bug: https://bugs.launchpad.net/horizon/+bug/1376738 It can be solved by patch https://review.openstack.org/#/c/125927/ 3. I can't delete "job" is because a job can only be deleted after all related "job_executions" deleted.

After the fresh devstack installation, I run a integration test to test the environment. After the test, cluster and tested edp jobs remains in my environment. Then I updated sahara to the lasted code. To make the newest code work, I also did : 1. manually download python-novaclient and by running "python setup.py install" to install it 2. run "sahara-db-manage --config-file /etc/sahara/sahara.conf upgrade head" Then I restarted sahara. I tried to delete things remained from last test from dashboard, but : 1. The table for "job_executions" can't be opened anymore. 2. When I try to delete "job", an error happened: 2015-03-18 10:34:33.031 ERROR oslo_db.sqlalchemy.exc_filters [-] DBAPIError exception wrapped from (IntegrityError) (1451, 'Cannot delete or update a parent row: a foreign key constraint fails (`sahara`.`job_executions`, CONSTRAINT `job_executions_ibfk_3` FOREIGN KEY (`job_id`) REFERENCES `jobs` (`id`))') 'DELETE FROM jobs WHERE jobs.id = %s' ('10c36a9b-a855-44b6-af60-0effee31efc9',) 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters Traceback (most recent call last): 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters File "/usr/local/lib/python2.7/dist-packages/sqlalchemy/engine/base.py", line 951, in _execute_context 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters context) 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters File "/usr/local/lib/python2.7/dist-packages/sqlalchemy/engine/default.py", line 436, in do_execute 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters cursor.execute(statement, parameters) 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters File "/usr/lib/python2.7/dist-packages/MySQLdb/cursors.py", line 174, in execute 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters self.errorhandler(self, exc, value) 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters File "/usr/lib/python2.7/dist-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters raise errorclass, errorvalue 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters IntegrityError: (1451, 'Cannot delete or update a parent row: a foreign key constraint fails (`sahara`.`job_executions`, CONSTRAINT `job_executions_ibfk_3` FOREIGN KEY (`job_id`) REFERENCES `jobs` (`id`))') 2015-03-18 10:34:33.031 TRACE oslo_db.sqlalchemy.exc_filters 2015-03-18 10:34:33.073 DEBUG sahara.openstack.common.periodic_task [-] Running periodic task SaharaPeriodicTasks.terminate_unneeded_transient_clusters from (pid=8084) run_periodic_tasks /opt/stack/sahara/sahara/openstack/common/periodic_task.py:219 2015-03-18 10:34:33.073 DEBUG sahara.service.periodic [-] Terminating unneeded transient clusters from (pid=8084) terminate_unneeded_transient_clusters /opt/stack/sahara/sahara/service/periodic.py:131 2015-03-18 10:34:33.108 ERROR sahara.utils.api [-] Validation Error occurred: error_code=400, error_message=Job deletion failed on foreign key constraint Error ID: e65b3fb1-b142-45a7-bc96-416efb14de84, error_name=DELETION_FAILED I assume this might be caused by an old horizon version, so I did : 1. update horizon code. 2. python manage.py compress 3. sudo python setup.py install 4. sudo service apache2 restart But these only make things worse. Now, when I click "Data Processing" on dashboard, there is no return action anymore. Anyone can help me here ? What I did wrong ? How can I fix this ? I tested sahara CLI, command like "sahara job-list" & "sahara job-delete" can still work. So I guess sahara is working fine. Thanks. -chen
