> The problem was discovered on the IGNITE-8355. 
> But *root cause* is the race on the start of the node discovery.
> The race happens because a joining node may start processing NodeAddMessage before processing local node's NodeAddFinishedMessage. Because of this, the local node will not have any constructed DiscoCache yet and NPE happens.
> We need to take a look at the workaround suggested in IGNITE-8355 and 
> 1) Check if any public API changes are needed on DiscoverySpi interface
> 2) Verify it works for ZookeeperDiscoverySpi.
