--------------------------------
Summary: [Java Broker] Add functionality to prevent unintended HA
node creation and mechanisms to react on intruder HA nodes
Key: QPID-5867
URL: https://issues.apache.org/jira/browse/QPID-5867
Project: Qpid
Issue Type: Improvement
Components: Java Broker
Reporter: Alex Rudyy
Assignee: Alex Rudyy
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.
