joining exchange

Hi, Igntrs!
When new node joins topology, it sends join TcpDiscoveryJoinRequestMessage
to arbitrary node N1.
If N1 is not coordinator, then it will resend to all nodes.

Why doesn't N1 send the message directly to coordinator ?

It think that the joining node sends its join-request message to the IP
address that was provided by the IP Finder, possibly in the configuration.

To send message to coordinator we need establish new connection, it is
preferably to use existing connections. Actually we tested this approach,
and on large clusters (> 200 nodes) it did not give start time improvments.

Thanks
