> * All JobMasters are LeaderContenders
> * Once a JobMaster is initialized, the very first thing it has to do is to
> start the leadership election service and contend for the leadership.
> * A JobMaster starts to perform its functionality when it grants the
> leadership.
> * If a JobMaster’s leadership is revoked, it will cancel all performed
> execution and release all acquired resources.
