hi，
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,没发同步导致超时的，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。
