Raquo; XML Feed. 初始化连接的问题: 在client与server之间握手建立连接的过程中, 如果握手失败, 执行所有的同步方法(比如create, getData等)将抛出异常. 自动恢复(failover)的问题: 当client与一台server的连接丢失,并试图去连接另外一台server时, client将回到初始连接模式. Session过期的问题: 在极端情况下, 出现ZooKeeper session过期, 客户端需要自己去监听该状态并重新创建ZooKeeper实例 . 对可恢复异常的处理:当在server端创建一个有序ZNode, 而在将节点名返回给客户端时崩溃, 此时client端抛出可恢复的异常, 用户需要自己捕获这些异常并进行重试. 重试机制:提供可插拔的重试机制, 它将给捕获所有可恢复的异常配置一个重试策略, 并且内部也提供了几种标准的重试策略(比如指数补偿). Heartbeat 项目是 Linux-HA 工程的一个组成部分，它实现了一个高可用集群系统。

Find xargs grep -r "power by johnny-zhuang". 通过这个场景我们可以学会find 以及 grep xargs 的基础操作了。 Date #输出当前时间 2016年07月20日 10:40:20.
