Hello. I need some advice. I have 1 client and 1 server. Ignite client connection to server take ~1 minute. And I don't understand why.
In server log I see next entry: 2018-11-09 16:34:16,471 [tcp-disco-client-message-worker-#16] DEBUG o.a.i.s.d.tcp.TcpDiscoverySpi - Redirecting message to client [sock=Socket[addr=/10.37.92.222,port=48843,localport=47500], locNodeId=c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, rmtNodeId=f4856174-de1d-4eae-ad85-80681f783955, msg=TcpDiscoveryNodeAddFinishedMessage [nodeId=f4856174-de1d-4eae-ad85-80681f783955, super=TcpDiscoveryAbstractMessage [sndNodeId=c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, id=a79abb8f661-c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, verifierNodeId=c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, topVer=7, pendingIdx=0, failedNodes=null, isClient=false]]] Client log: 2018-11-09 16:35:06.585 DEBUG 10 --- [-sock-reader-#3] o.a.i.spi.discovery.tcp.TcpDiscoverySpi : Message has been received: TcpDiscoveryNodeAddFinishedMessage [nodeId=f4856174-de1d-4eae-ad85-80681f783955, super=TcpDiscoveryAbstractMessage [sndNodeId=c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, id=a79abb8f661-c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, verifierNodeId=c86fe162-0a55-4aaa-a2cd-f2ea1c644b5f, topVer=7, pendingIdx=0, failedNodes=null, isClient=false]] Difference is 50 seconds.

Thank you. PS. This is kubernetes.
