storm集成kafka zk保存消费offset

[大王有金角111111111111111]

代码:
final ZkHosts zkHosts = new ZkHosts("192.168.217.35:2181,192.168.217.44:2181,192.168.217.45:2181");
SpoutConfig spoutConfig = new SpoutConfig(zkHosts, "test1", "/myOffSet", "myTest2");
spoutConfig.zkServers = Arrays.asList("192.168.217.35","192.168.217.44","192.168.217.45");
spoutConfig.zkPort = 2181;
问题:
jstorm版本：2.1.1
storm-kafka版本: 0.10.2

zookeeper配置没有问题，集群拓扑启动后，在zookeeper的/根目录中，没有自动创建保存消费kafka的《/myOffSet》目录
