Description Luigi Toscano 2017-09-08 12:12:41 UTC

Description of problem:
Due to some change forced by the switch to newer keystone version (see https://review.openstack.org/#/c/485521/), the trust mechanism in Sahara uses the configuration values from the section [keystone_authtoken] (this may change in the future).
Two of the values that are needed by Sahara (user_domain_name and project_domain_name) are not filled (even with default values) by default by puppet-sahara. sahara-engine tries to read them when starting to create a cluster (two KeyError exceptions visible in sahara-engine.log).

A simple fix is change the function which retrieves those values to accept a default value (which is easier than changing all systems which writes sahara.conf).

A fix was proposed upstream but it's not yet in stable/pike; this is to ensure that it will be imported.

Additional info:

Comment 2 Luigi Toscano 2017-09-08 16:48:29 UTC

Fix merged in master, backport for pike proposed.

Comment 3 Paul Grist 2017-09-13 00:46:47 UTC

Stable Pike merged, moving to POST to move this forward.

Comment 6 Luigi Toscano 2017-10-20 09:03:49 UTC

The patch landed in a format that could be tested (and it's not going away from that branch).

It is now possible to spawn clusters.

Tested with a containerized deployment (Spark and CDH 5.7):
openstack-sahara-api-7.0.1-0.20170912230210.bdc7d83.el7ost.noarch
openstack-sahara-engine-7.0.1-0.20170912230210.bdc7d83.el7ost.noarch
