             Summary: Symlinks are not followed when requesting resources from Ambari's resources entry point
                 Key: AMBARI-23695
                 URL: https://issues.apache.org/jira/browse/AMBARI-23695
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.6.2
            Reporter: Robert Levas
            Assignee: Robert Levas
             Fix For: 2.6.2


Symlinks are not followed when requesting resources from Ambari's resources entry point.

For example if the Beacon mpack is installed, a symlink is made from /var/lib/ambari-server/resources/mpacks/beacon-engine.mpack-1.1.0.0/addon-services/BEACON/1.1.0 to /var/lib/ambari-server/resources/stacks/HDP/2.6/services/BEACON:

}

When this occurs, the stack definitions from BEACON are not able to be cached by the Ambari agents.
