[jira] [Created] (IGNITE-7506) GridClusterStateProcessor#compatibilityMode flag never gets reset to false

             Summary: GridClusterStateProcessor#compatibilityMode flag never gets reset to false
                 Key: IGNITE-7506
                 URL: https://issues.apache.org/jira/browse/IGNITE-7506
             Project: Ignite
          Issue Type: Bug
            Reporter: Sergey Chugunov
            Assignee: Sergey Chugunov


When Ignite node of version 2.4+ joins cluster with older versions of Ignite running it sets *compatibilityMode* flag to handle **cluster state in a special way (excluding BaselineTopology from discovery exchange process and so on).

But when all old nodes are turned off there is no way except full cluster restart to enable setting very first **BaselineTopology.

This should be addressed and some way to exit compatibilityMode without full cluster restart should be provided.
