>             Project: Ignite
>          Issue Type: Improvement
>    Affects Versions: 2.9.1
>            Reporter: Alexandr Shapkin
>            Assignee: Alexandr Shapkin
>            Priority: Major
>              Labels: discovery
>             Fix For: 2.11
>
>          Time Spent: 10m
>  Remaining Estimate: 0h

> Scenario:
> Kubernetes world, a server node, a k8s service, and a thick client. The 
> client is subscribed to EVT_CLIENT_NODE_DISCONNECTED event and is connected 
> to the server node.
> When a service goes down alongside the server, no 
> EVT_CLIENT_NODE_DISCONNECTED is caught and the client reports only about a 
> socket exception and inability to resolve IP addresses from the services, 
> cause k8s resource is not available. The DEBUG logs (attached) show that 
> discovery is constantly trying to use KubernetesIpFinder and restore the 
> connection.
> Expected:
> Discovery realizes that a client is disconnected, no more reconnection 
> attempts happen and EVT_CLIENT_NODE_DISCONNECTED is thrown.
> Solution:
> Count resolution attempts and if it’s more than the threshold (2 if 
> failuredetectiontimeout is not configured, otherwise #reconnCount) give up 
> and invoke disconnection logic
