Hi, SensorDataGenerator doesn't start Ignite node, so you should have only 1 server and 1 client node in topology:
Topology snapshot [ver=2, servers=1, clients=1, CPUs=4, heap=6.8GB] Check it, most probably you have one more running server node on your host. Also, your topology version is 46, it's strange, looks like nodes failed and started nearly 20 times.
