> Key: SLING-10489
> URL: https://issues.apache.org/jira/browse/SLING-10489
> Project: Sling
> Issue Type: Task
> Components: Discovery
> Affects Versions: Discovery Oak 1.2.34
> Reporter: Stefan Egli
> Assignee: Stefan Egli
> Priority: Major
> Fix For: Discovery Oak 1.2.36
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Discovery.oak requires that both Oak and Sling are operating normally in
> order to declare victory and announce a new topology.
> The startup phase is especially tricky in this regard, since there are
> multiple elements that need to get updated (some are in the Oak layer, some
> in Sling) :
> * lease & clusterNodeId : this is maintained by Oak
> * idMap : this is maintained by IdMapService (Sling)
> * leaderElectionId : this is maintained by OakViewChecker (Sling)
> * syncToken : this is maintained by SyncTokenService (Sling)
> Situations have seen where Oak is startup up fine, but higher level (eg
> Sling) bundles were not activated within a reasonable amount of time. This
> lead to discovery staying in TOPOLOGY_CHANGING state for longer than expected.
> There should be a mechanism that ignores (suppresses) newly joining instances
> if they start up only partially. However, after a certain timeout this
> mechanism should give up.
