[jira] [Created] (KNOX-2909) Ignore CORE_SETTINGS service discovery

Sandor Molnar created KNOX-2909:
-----------------------------------

             Summary: Ignore CORE_SETTINGS service discovery
                 Key: KNOX-2909
                 URL: https://issues.apache.org/jira/browse/KNOX-2909
             Project: Apache Knox
          Issue Type: Bug
          Components: cm-discovery
    Affects Versions: 2.1.0
            Reporter: Sandor Molnar
            Assignee: Sandor Molnar
             Fix For: 2.1.0


As a side-effect of KNOX-2899, Knox tries to scan the entire cluster (again) during service discovery. In case CM is not reachable, but previous discovery results are available in the service discovery repository (an in-memory Caffeine cache), discovery fails, because it tries to get roles for a new CM service called {{{}CORE-SETTINGS{}}}.

This is a special CM service, which Knox's CM service discovery should completely ignore.
