> Now in yarn mode, there're three places using zookeeper client(web monitor, jobmanager and resourcemanager) in ApplicationMaster/JobManager, while there're two in TaskManager. They create new one zookeeper client when they need them.
> I believe there're more other places do the same thing, but in one JVM, one CuratorFramework is enough for connections to one zookeeper client, so we need a singleton to reuse them.
