canal server在zookeeper的节点：

[zk: localhost:2181(CONNECTED) 15] get /otter/canal/destinations/example/running  
{"active":true,"address":"10.20.144.51:11111","cid":1}

目前一台机器，判断当前是否为工作节点，是通过cid是否和本机的id相同来判断，但目前cid这信息在启动canal server没有严格校验是否有重复，导致两台机器都认为是自己本机，对于后续的命令控制操作有风险

解决：将判断是否本机的操作，修改为基于address是否相同来判断，ip+port可以唯一定义一个jvm
