zookeeper报错:NoNodeException: KeeperErrorCode = NoNode for /consumes/xxx/xxx Node does not exist
登录到zookeeper服务器，查看node信息，如果不存在，看为什么不存在？
./zkCli.sh -server localhost:2181
create /consumers/xxx/xxx test
zk操作命令：
ls /consumers/xxx/xxx get /consumers/xxx/xxx set /consumers/xxx/xxx test create /consumers/xxx/xxx test
