KNOX-2909 - Ignoring CORE_SETTINGS CM service discovery (#758)
> 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
> Priority: Major
> Fix For: 2.1.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
