Open Stack

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.


Thanks.

Subject: [openstack-dev] [Sahara][Horizon] Can't open "Data Processing" panel after update sahara & horizon

Hi all,

I'm working under Ubuntu14.04 with devstack.

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:

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.
