[jira] [Updated] (OAK-8683) The async indexing thread runs on all cluster nodes if the DefaultWhiteBoard is used.

     [ https://issues.apache.org/jira/browse/OAK-8683?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Manfred Baedke updated OAK-8683:
--------------------------------
    Description: In the absense of an OSGi framework, a newly created Oak instance wouldn't use the OsgiWhiteBoard, but instead fall back to it's own internal implementation extending DefaultWhiteBoard. The WhiteboardUtils.ScheduleExecutionInstanceTypes are then completely ignored when registering the AsyncIndexUpdate job (which makes sense, since Oak doesn't understand it's own RUN_ON_LEADER hint), resulting in async indexing threads running on all cluster nodes and fighting for  the index update lease.  (was: In the absense of an OSGi framework, a newly created Oak instance wouldn't use the OsgiWhiteBoard, but instead fall back to it's own internal implementation extending DefaultWhiteBoard.
