> Issue Type: Bug

>
> Using Apache Curator as the Zookeeper library causes an issue where Aurora is
> unable to elect a leader if Zookeeper loses quorum for an extended period of
> time.
> Scheduler seems to crash around:
> {{W0802 14:01:14.436 [TaskEventBatchWorker, SchedulerLifecycle] Failed to
> leave leadership:
> org.apache.aurora.common.zookeeper.SingletonService$LeaveException: Failed to
> abdicate leadership of group at /aurora/scheduler }}
> When the init system brings the scheduler back up, it is unable to elect a
> leader if ZK is still down.
> Once the scheduler enters this state, it is unable to snap out of it until it
> is manually restarted.
