Summary: Conflict resolution consistent hash should not include nodes that are not in the merged cluster view
Key: ISPN-9014
URL: https://issues.jboss.org/browse/ISPN-9014
Project: Infinispan
Issue Type: Bug
Components: Test Suite - Core
Affects Versions: 9.2.1.Final
Reporter: Dan Berindei
Assignee: Dan Berindei
Fix For: 9.3.0.Alpha1
Conflict resolution fails when trying to read entries from nodes that are not in the JGroups cluster view, and this causes random failures in {{ClusterListenerDistTest.testClusterListenerNodeGoesDown random}}.
# NodeA leaves the cluster, but still manages to start a rebalance with [NodeB, NodeC] (topology id 11)
# One node doesn't receive topology 11, so NodeB becomes coordinator and starts conflict resolution with all 3 nodes in the pending CH (topology 12)
# Conflict resolution fails because NodeB and NodeC can't read the entries from NodeA
# {{onPartitionMerge}} also queued a rebalance, so NodeB starts a new rebalance without canceling the previous rebalance first (topology 13)
# Because there is no reset topology, NodeB thinks it already requested all the segments for NodeC's in topology 11, so it doesn't add any new inbound transfer
# NodeC's state response arrives on NodeB with topology 11, NodeB discards it, and state transfer hangs.
