---------------------------------

             Summary: Cancelled segment transfer causes future entry transfer to be ignored
                 Key: ISPN-4154
                 URL: https://issues.jboss.org/browse/ISPN-4154
             Project: Infinispan
          Issue Type: Bug
          Components: State Transfer
    Affects Versions: 7.0.0.Alpha1
            Reporter: Radim Vansa
            Assignee: Dan Berindei
            Priority: Critical


Distributed transactional cache.

1) Coordinator is gracefully leaving the cluster, sends a REBALANCE_START with topologyId 14, ST begins.
2) Node receives chunk from segment X, writes entry K=V to the container.
3) New coordinator jumps in with CH_UPDATE topology 16
4) Node receives CANCEL_STATE_TRANSFER and cancels transfer of segment X, invalidating K. In CommitManager, this operation is tracked and DiscardPolicy is set to DISCARD_STATE_TRANSFER for key K.
5) New coordinator starts rebalance with topology 17
6) Node starts new ST for segment X
7) Node receives the X: K=V, but in CommitManager it finds out that the policy is set to DISCARD_STATE_TRANSFER and ignores this update.

Result: entry value is lost on some node.
