Neeraj, You probably enabled debug logging on the following package: *org.apache.ignite.spi.discovery.tcp*
There is nothing wrong in these exceptions actually. The first connection refused exception happens because there are two hosts in the IP finder configuration, but when you start the first node, nobody is bound to the discovery port on the second host. So, you get *"Connection refused" *exception, when discovery SPI is trying to connect to the second host. If you see a message like this, then it means, that discovery finished its work successfully: *Topology snapshot [ver=1, servers=1, ...]* You can disable debug logging not to see these exceptions. The second exception is also doesn't mean anything bad. It only means, that some object was transferred to this node, and connection was suddenly closed. So, none of these exceptions mean anything bad.
