Aleksey Plekhanov commented on IGNITE-12398:
--------------------------------------------
[~ravimsc], can you please provide more information about your case? Where do
you start visor, inside S3 or outside? Do you set some additional properties in
visor configuration ({{IgniteConfiguration.LocalHost}} for example)?
I've checked {{getAddress()}} method with address patterns you provided, and
this method return not null for such values.
I found some problems with daemon nodes (visor uses deamon node to join
cluster), they joined to ring (like server nodes) instead of joining like a
client. When joined to ring IpFinder.registerAddresses is invoked and if some
of addresses passed by visor is unresolvable, exception like yours can be
thrown (I can't imagine how it can happen since Ignite uses IP address if host
is unresolvable). But you can workaround it, just set ClientMode = true in
visor configuration and visor will not join the ring and will connect to
cluster like a client.
I think this ticket is not a blocker (workaround exists, we can't reproduce
it). I've set priority to "critical" and have targeted the ticket to the next
release.
