canal+zookeeper 集群 客户端第一次启动成功第二次不能启动

3台canal +3台zookeeper，搭建好环境后用源码中的ClusterCanalClientTest类测试 并能正常消费。关闭这个客户端后再ClusterCanalClientTest类测试就不能起来程序一直阻塞，发现ZOOKEEPER中的信息未变导致不能正常启动

[zk: localhost:2181(CONNECTED) 6] get /otter/canal/destinations/example/1001/running {"active":true,"address":"192.168.0.59:54224","clientId":1001} cZxid = 0x20000001a ctime = Thu Nov 01 22:56:35 EDT 2018 mZxid = 0x200000031 mtime = Thu Nov 01 23:17:07 EDT 2018 pZxid = 0x20000001a cversion = 0 dataVersion = 2 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 62 numChildren = 0
