Open Stack

Hi Li,

  I am using a fresh devstack with Horizon deployed as part of devstack.
I am running Sahara separately from the command line from the git
sources (master branch).

  I use a little script to register the Sahara endpoint so that Horizon
sees it.
The only change I had to make was to register the service type  as
data-processing instead
of data_processing (below). Other than that, I don't have any problems.

  If you are really stuck, you can always wipe out the database and
rebuild to get beyond the issue.
With mysql I use

$ mysqladmin drop sahara
$ mysqladmin create sahara
$ sahara-db-manage --config-file /etc/sahara/sahara.conf upgrade head

If this error is reliably reproducible, would you create a bug in
launchpad with detailed steps to reproduce?
It's not clear to me what the issue is.

Thanks,

Trevor
