>             Project: Ignite
>          Issue Type: Bug
>          Components: thin client
>    Affects Versions: 2.16
>            Reporter: Pavel Tupitsyn
>            Priority: Major
>             Fix For: 2.18

>
> * Thick clients have thin client connector enabled by default
> * *ClientClusterGroupGetNodesEndpointsResponse* excludes client nodes
> As a result:
> * Thin client connects to a thick client node
> * Gets node endpoints - current connection is not there
> * Thin client closes current connection immediately
> The following test demonstrates the problem. While *setForceServerMode* is deprecated, there could be other reasons for other nodes to be unreachable.
> {code:java}
>     @Test
>     public void testConnectToThickClient() {
>         TcpDiscoverySpi discoSpi = new TcpDiscoverySpi()
>                 .setIpFinder(new TcpDiscoveryVmIpFinder(true))
>                 .setForceServerMode(true);
>         IgniteConfiguration igniteCfg = new IgniteConfiguration()
>                 .setDiscoverySpi(discoSpi);
>         try (Ignite ignored = Ignition.start(igniteCfg);
>              IgniteClient client = Ignition.startClient(new ClientConfiguration())
>         ) {
>             assertNotNull(client);
>         }
>     }
> {code}
> Potential solutions:
> * Disable client connector on thick client nodes by default (breaking change?)
> * Fix *ClientClusterGroupGetNodesEndpointsResponse* to include thick client nodes if connector is enabled, and let the client decide whether to connect to them or not
