Hello, Please pass all known server node addresses to ClientConfiguration.setAddresses.
E.g. if everything is on one machine, for 3 servers it'll be setAddresses("127.0.0.1:10800", "127.0.0.1:10801", "127.0.0.1:10802") On Mon, Mar 29, 2021 at 3:23 PM Максим Плотников <mplotni...@naumen.ru> wrote: > Hello! > > > > I'm dealing with Apache Ignite at the moment.
