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

             Summary: L1 invalidation fails when some of the requestors have left the cluster
                 Key: ISPN-1839
                 URL: https://issues.jboss.org/browse/ISPN-1839
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Cache
    Affects Versions: 5.1.0.FINAL
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 5.1.1.FINAL


When a node leaves the cluster, it remains in the list of requestors for all the entries that it retrieved from other nodes. When those entries are updated, their owners try to invalidate them on the leaver. The invalidation command fails because the target has left, and this causes the entire put operation to fail.

This can be seen in some of the HotRod server tests, e.g. HotRodDistributionTest:
