use curator in storm cluster, receive multi notification when childnode change










0















enviroment:



zookeeper version: 3.4.12,
curator version:2.12.0,
storm version:1.2.2



storm configuration: 2 workers, 1 spout, 1 bolt



describe:



when storm topology start, spout would start a thread to watch mynode,



curator.getChildren().usingWatcher(this).forPath("/mynode")


bolt would register a node,



client.create().withMode(CreateMode.EPHEMERAL).withACL(ZooDefs.Ids.OPEN_ACL_UNSAFE).forPath("/mynode/hello-"UUID.randomUUID().toString());


Through log, spout would receive multi notification, sometimes more than one hundred in one second.



I try to create node on /mynode manually, there are also multi notifications.



zookeeper server log:
zookeeper server log



does this matter?



I wanna one notification after one update, what can I do?
