             Summary: DistributedStreamIteratorTest.testLocallyForcedStream random failure
                 Key: ISPN-7997
                 URL: https://issues.jboss.org/browse/ISPN-7997
             Project: Infinispan
          Issue Type: Bug
          Components: Test Suite - Core
    Affects Versions: 9.1.0.Beta1
            Reporter: Dan Berindei
            Assignee: Dan Berindei
            Priority: Critical


The test uses the {{MagicKey(primary, backup...)}} constructor with only 16 segments and with the default {{SyncConsistentHashFactory}}. Since SCHF is based on the random addresses of the nodes, the combination of owners is not always possible:
