You used try-with-resources block when starting the instance:
try(Ignite ignited =
Ignition.start(System.getProperty(IGNITE_CONFIG_FILE_PROP))){
ignited.active(true);
ctIgnite = ignited;
} When this block is completed, instance is closed, therefore you get exceptions afterwards. Get rid of the try block and just run Ignition.start to start a node. -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
