[jira] [Created] (IGNITE-3973) Nodes can form separate clusters with TcpDiscoveryMulticastIpFinder

Semen Boikov created IGNITE-3973:
------------------------------------

             Summary: Nodes can form separate clusters with TcpDiscoveryMulticastIpFinder
                 Key: IGNITE-3973
                 URL: https://issues.apache.org/jira/browse/IGNITE-3973
             Project: Ignite
          Issue Type: Bug
          Components: general
    Affects Versions: 1.7
            Reporter: Semen Boikov
            Assignee: Semen Boikov
            Priority: Critical
             Fix For: 1.8


Currently TcpDiscoveryMulticastIpFinder on start sends mcast address request and stops wait when at least one remote address is received.
This scenario is possible:
- 4 nodes start concurrently
- node1 receive first address of node2, node2 from node1
- node3 receive first address of node4, node4 from node3
- node1/node2 and node3/node4 can form separate clusters
