Apache Curator 2.8.0 發布，簡化 zookeeper 客戶端

zookeeper 的客戶端調用過于復雜，Apache Curator 就是為了簡化zookeeper客戶端調用而生，利用它，可以更好的使用zookeeper。

Apache Curator 2.8.0 發布，此版本的 Apache Curator Java 庫讓 Apache Zookeeper 使用起來更方便，詳細更新信息如下：

Bug 修復：

• [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

性能改進：

• [CURATOR-203] - ChildReaper can be unstable when there are large ZNodes

• [CURATOR-204] - Use the latest apache parent pom
