Hi, This is a known issue and is already fixed: https://issues.apache.org/jira/browse/IGNITE-8134
After calling cluster.active(true), cluster nodes form baseline topology and currently it's impossible to deploy services from node out of topology on active cluster. Will be available in future Ignite versions. Best regards, Anton -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
