> Key: QPID-5867
> URL: https://issues.apache.org/jira/browse/QPID-5867
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Alex Rudyy
> Assignee: Keith Wall
>
> Add functionality to prevent unintended node creation and mechanisms to react on intruder nodes
> New HA VH attribute permittedNodeList
> Nodes register the contents of this attribute as app-state
> On adding a new node to the griup, the node must check to see its node address is included in the app-state, if not, refuse to join
> All nodes periodically (BDBHAVHN has a thread dedicated to the purpose or reuse node discovery thread?) check to see if nodes exist that do not appear in the app-state. If so VHN will close env and go into ERROR state.
> If in management mode don't periodically check the PNL, thus allowing an intruder to be removed.
