Time Out 是版本不兼容的问题吗

我使用了server－V1.0.22最新版、client－V1.0.21 仓库取的依赖jar出现了莫名的超时问题，我的zookeeper其他应用支持的很好zkServer=cdh3:2181,cdh1:2181,cdh5:2181 。

使用zookeeper调度出现超时现象，clinet一直联不通, 用Simple方式就没有问题，超时抛的错误如下。

debug到BooleanMutex这个类,这个get没法同步导致超时的，具体原因没有找到：

public void get() throws InterruptedException { this.sync.innerGet(); }

后来把server换成V1.0.21还是不行。 是不是在zk里保留了版本不兼容的信息。 是21client不能配合22的server吗？ 谢谢。

这个错误怎么解读？ ERROR ZkEventThread - Error handling event ZkEvent[Data of /otter/canal/destinations/user/1001/running changed sent to com.alibaba.otter.canal.client.impl.running.ClientRunningMonitor$1@5789b4d3]

zk Node [/otter/canal/destinations/user/1001/running ] 是: {"active":true,"address":"10.1.193.0","clientId":1001}
