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

             Summary: Compatibility mode: HotRod client sends request to wrong owner
                 Key: ISPN-5981
                 URL: https://issues.jboss.org/browse/ISPN-5981
             Project: Infinispan
          Issue Type: Bug
          Components: Remote Protocols
    Affects Versions: 8.1.0.Beta1, 8.0.1.Final
            Reporter: Dan Berindei
         Attachments: GetAllCompatDistTest.java

The HotRod client computes the hash on the serialized key, i.e. {{MurmurHash3.hash(obj2bytes(key))}}, but the server decides the entry location based on the unmarshalled key, i.e. {{MurmurHash3.hash(key.hashCode())}}.

I've modified {{GetAllCompatDistTest}} (attached) to test if there are any {{ClusteredGetCommand}}s being sent for {{RemoteCache.get(key)}} operations, and it finds quite a few:
