Fixed In Version:	openstack-sahara-2014.2.3-3.el7ost	Doc Type:	Bug Fix
Doc Text:	Previously, the HDP plug-in installed the 'Extra Packages for Enterprise Linux (EPEL)' repository on cluster generation, even though neither the plug-in nor the saraha-image-elements package used the repository for any purpose. Consequently, a superfluous and potentially error-prone step was introduced into HDP cluster generation; in addition, these clusters may potentially update to unsupported packages. With this update, the repository is no longer installed by the HDP plug-in.	Story Points:	---

Description Elise Gafford 2015-06-15 15:49:00 UTC

Description of problem:
The HDP plugin installs EPEL as part of its installation flow. Providing that a generated image is used, nothing is installed from this repository, but failure to install it or read its metadata will result in a failed cluster. Empirical tests verify that this installation can be wholly removed.


How reproducible:
100% (cluster creation failure is extremely sporadic, but package installation is universal.)


Steps to Reproduce:
1. Create any cluster using the HDP plugin.
2. Await cluster 'active' state.
3. Verify that 'epel.repo' exists in /etc/yum.repos.d/ on any cluster node.

Actual results:
EPEL repo exists on cluster nodes (though a yum list reveals that no package is installed from this repo.)

Expected results:
EPEL is uninstalled on RHEL HDP cluster nodes.

Comment 6 Luigi Toscano 2015-08-17 17:31:32 UTC

After this change, the instances of RHEL6 started by Sahara to build an HDP 2.0.6 cluster do not have the epel repositories enabled.

Verified with:
openstack-sahara-2014.2.3-3.el7ost.noarch
python-saharaclient-0.7.6-1.el7ost.noarch
