Sergey Chugunov commented on IGNITE-10926:
------------------------------------------
[~NSAmelchev],
I reviewed the patch and it looks reasonable for me.
The only thing that bothers me is that semantics of RECONNECT event was
weakened: if earlier the event was fired only if client node has finished
joining process, but now it is fired always when client restores its connection
to the cluster.
[~agoncharuk], do you think it may cause any issues?

> {{ZookeeperDiscoveryImpl#cleanupPreviousClusterData}} can delete alive node
> of a client in case of low internal order.
> Steps to reproduce:
> 1. Start server and client.
> 2. Stop the server and wait for the client disconnected.
> 3. Start and stop the server. The server hasn't time to process client join
> request.
> 4. Start server. It will delete alive client node because the client has low
> internal order. The client will never connect.
