> Key: IGNITE-1208
> URL: https://issues.apache.org/jira/browse/IGNITE-1208
> Project: Ignite
> Issue Type: Bug
> Reporter: Yakov Zhdanov
> Assignee: Sergey Evdokimov
>
> When there are problems with multicast, servers running on local node are
> able discover each other, but clients are not.
> I notice the difference in MulticastIpFinder logic for clients and servers,
> but I could not 100% reproduce it.
> Observed:
> # When clients are started and no servers are up, clients warn user that IP
> finder returned empty address collection and hangs forever. Clients join does
> not finish even if servers come up.
> # Two or more servers are able to discover each other.
> # When servers are started first, clients are able to join.
> This is hardly reproducible on most environments, but Dmitiry S. has such
> environment.
> Sergey Evokimov, can you please create build with debug logs and have Dmitry
> S. run it for you?
