> Now in yarn mode, if we use zookeeper as high availability choice, it will
> create a election service to get a leader depending on zookeeper election.
> When zookeeper leader crashes or the connection between JobManager and
> zookeeper instance was broken, JobManager's leadership will be revoked and
> send a Disconnect message to TaskManager, which will cancle all running tasks
> and make them waiting connection rebuild between JM and ZK.
> In yarn mode, we have one and only JobManager(AM) in same time, and it should
> be alwasy leader instead of elected through zookeeper. We can introduce a new
> leader election service in yarn mode to achive that.
