Apache Curator
Curator提供了对zookeeper客户端的封装，并监控连接状态和会话session，特别是会话session过期后，curator能够重新连接zookeeper，并且创建一个新的session。
Apache Curator 2.8.0 发布，此版本的 Apache Curator Java 库让 Apache Zookeeper 使用起来更方便，详细更新信息如下：
Bug 修复：
[CURATOR-154] - PersistentEphemeralNode May Fail to Apply Updated Data
[CURATOR-164] - curator-x-discovery: unregisterService is not guaranteed to remove the service, due to reconnectListener concurrency issue
[CURATOR-168] - Background protected mode incorrectly sets Event name to just ZNode name. Should be full path.
[CURATOR-173] - InterProcessSemaphoreV2 nodes not reapable
[CURATOR-182] - TreeCache breaks when root node is removed
[CURATOR-183] - TreeCache not properly handling repeated add/removal of root node
[CURATOR-187] - ChildReaper does not respect built in leader election
[CURATOR-190] - PersistentEphemeralNode.Mode.PROTECTED_EPHEMERAL creates new node on recreate
[CURATOR-202] - LeaderSelector node is not removed on connection loss if reconnected to the same session
[CURATOR-210] - Unit tests using server.close() are fragile.
[CURATOR-211] - Fix InterProcessReadWriteLock#readLockPredicate() index validation issue
性能改进：
[CURATOR-203] - ChildReaper can be unstable when there are large ZNodes
[CURATOR-204] - Use the latest apache parent pom
