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

             Summary: Joining node should be discarded in case discovery exchange data can't be deserialized
                 Key: IGNITE-1238
                 URL: https://issues.apache.org/jira/browse/IGNITE-1238
             Project: Ignite
          Issue Type: Bug
          Components: general
    Affects Versions: 1.1.4
            Reporter: Valentin Kulichenko
            Assignee: Valentin Kulichenko
            Priority: Critical
             Fix For: ignite-1.4


Currently a node will join even if unmarshalling fails (see {{TcpDiscoverySpi.onExchange()}} method, which can cause unexpected behaviour. For example, a continuous query listener is not deployed on some nodes in topology. Everything works, but some updates are lost. We should discard the node in this case and give a good error message to user with information on how to fix it properly.
