Hi, I have 2 virtualbox guest OS'es (CentOS7 64-bit) , each having firewalld stopped and disabled. The nodes are axlrate-node-1 and axlrate-node-2. I have updated default-config.xml in both servers My default-config.xml looks like below : ---------------------------------------------------------default-config.xml @ axlrate-node-1--------------------------------------------------------- <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd";> <!-- Alter configuration below as needed. --> <bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration"> <property name="discoverySpi"> <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi"> <property name="localAddress" value="axlrate-node-1"/> <property name="ipFinder"> <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder"> <property name="addresses"> <list> <!-- Explicitly specifying address of a local node to let it start and operate normally even if there is no more nodes in the cluster.

Any clues on what the issue could be ? I am especially worried about the Marshaller errors. There are no custom classes being used here. It is purely using Ignite installed JAR's only.
