             Summary: Write to Distributed Metastorage should throw exception on client if client is not connected to topology
                 Key: IGNITE-14575
                 URL: https://issues.apache.org/jira/browse/IGNITE-14575
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.10
            Reporter: Semyon Danilov
            Assignee: Semyon Danilov


Reference to Distributed Metastorage can be obtained on client that hasn't connected to any server node yet.

The reference allows to send write request that will be completed after client connect when Tcp Discovery is used and dropped on ZK Discovery.

To make API more reliable we need to change this behavior: when client is not connected to any server (because there are no servers in topology yet or because it has disconnected from topology) all incoming write or cas requests should be dropped, appropriate exception should be thrown.
