             Summary: Refresh client attributes during reconnect
                 Key: IGNITE-4641
                 URL: https://issues.apache.org/jira/browse/IGNITE-4641
             Project: Ignite
          Issue Type: Improvement
          Components: general
    Affects Versions: 1.8
            Reporter: Valentin Kulichenko
             Fix For: 1.9


Currently, when client disconnects and reconnects, it is forced to do that with the exact same set of attributes. However, there can be a component that wants to update attribute(s) in {{onDisconnected}} method, so that node reconnects with new attributes. To make sure this happens we need to refresh attributes before reconnecting. Most likely this should happen in {{TcpDiscoveryNode.clientReconnectNode()}} method which should acquire attributes via {{GridKernalContext.nodeAttributes()}}.

Typical use case is a security token that can expire. Security processor implementation may want to refresh the token in case of disconnect, but this is not possible now.
