-----------------------------------
Summary: Partially started instance suppression can lead to
unwanted leader loss
Key: SLING-11450
URL: https://issues.apache.org/jira/browse/SLING-11450
Project: Sling
Issue Type: Bug
Components: Discovery
Affects Versions: Discovery Oak 1.2.36, Discovery Base 2.0.12
Reporter: Stefan Egli
Assignee: Stefan Egli
Fix For: Discovery Base 2.0.14, Discovery Oak 1.2.38
SLING-10489 introduced "partial startup suppression" sometimes also referred to
as "joinerdelay" (even though the latter is actually a subfeature of the
former).
With this suppression enabled (it is disabled by default), upon a topology
change the leader instance can loose its leader status even though it did not
actually leave the topology or crash. This is against the discovery API
contract, which says that the leader stays leader until it crashes.
