             Summary: LocalTopologyManager should not install a reset topology before conflict resolution
                 Key: ISPN-8993
                 URL: https://issues.jboss.org/browse/ISPN-8993
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 9.2.0.Final
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 9.2.1.Final


When the coordinator changes, either because the old one left or because there was a merge, the new coordinator first resets any ongoing rebalance, and then starts a rebalance with the new members. But some nodes could see the post-merge rebalance before the post-merge reset, and they need to reset any old data or inbound transfers first. 

[LocalTopologyManagerImpl|https://github.com/infinispan/infinispan/blob/22a1fc0b2dae9dd9c5fdedc05b2d9daf9d292308/core/src/main/java/org/infinispan/topology/LocalTopologyManagerImpl.java#L418] is responsible for faking that reset topology update, in order to keep StateConsumerImpl simpler. The problem is that LocalTopologyManagerImpl also creates a reset topology update if the new coordinator started conflict resolution.
