不同版本Cassand的CCM问题

Question

Cassandra clustrer 2.2.9在CCM中运行良好，但当我使用3.7创建集群时，它抛出以下错误：

C:\Users\Admin>ccm start
Started: node1 with pid: 4844
Started: node3 with pid: 4060
Started: node2 with pid: 2172
Started: node4 with pid: 5816

C:\Users\Admin>ccm stop

SUCCESS: The process with PID 4060 has been terminated.
SUCCESS: The process with PID 2172 has been terminated.
