Exception in Tomcat while datahub setup

Hi , I am getting exception in Tomcat server after setting up datahub . Looks like related to tcp/ip connection :

22-Jun-2018 11:33:30.602 WARNING [hz._hzInstance_1_datahub-hazelcast.IO.thread-in-0] com.hazelcast.nio.tcp.TcpIpConnection.null [127.0.0.1]:5701 [datahub-hazelcast] [3.7.2] Connection[id=13, /127.0.0.1:59093->/127.0.0.1:5702, endpoint=[127.0.0.1]:5702, alive=false, type=NONE] closed.

Any help is appreciated.

Hi ,

which version of DataHub are you using ? if it is 6.5+ then please use below properties in the local.properties of the datahub.

datahub.hz.port.number=7070

datahub.cluster.node.akka-port=2552

datahub.cluster.node.hostname=127.0.0.1

datahub.hz.port.autoincrement=false
