Description of problem:
Scenario tests (from master commit bce48970e81baf61a07d43cca27e1e4699ac62a0) fails with a CDH 5.3.0 RHEL 7.2 image. The cluster is created but the jobs stays in RUNNING state "forever" (raising the waiting time for jobs to 7200 seconds did not help).

Please note that the tests do *pass* for CDH 5.4.0 and HDP 2.0.6.

Version-Release number of selected component (if applicable):
openstack-sahara-common-3.0.0-5.el7ost.noarch
openstack-sahara-engine-3.0.0-5.el7ost.noarch
openstack-sahara-api-3.0.0-5.el7ost.noarch

The images have been generated with 
sahara-image-elements-3.0.0-3.el7ost.noarch

Apparently no relevant information in sahara-api and sahara-engine logs.

How reproducible:
$ python sahara/tests/scenario/runner.py --verbose -V scenario.ini etc/scenario/sahara-ci/credentials.yaml.mako etc/scenario/sahara-ci/edp.yaml.mako etc/scenario/sahara-ci/cdh-5.3.0.yaml.mako
