Bill Farner updated AURORA-51:
------------------------------
Summary: Scheduler stalls during startup if storage recovery fails (was:
Scheduler stalls during startup if )
> Scheduler stalls during startup if storage recovery fails
> ---------------------------------------------------------
>
> Key: AURORA-51
> URL: https://issues.apache.org/jira/browse/AURORA-51
> Project: Aurora
> Issue Type: Bug
> Components: Scheduler
> Reporter: Bill Farner
> Assignee: Bill Farner
> Priority: Critical
>
> If SchedulerLifecycle encounters a RuntimeException while initializing
> storage, it takes no action to abort. The result is a leader in ZK that will
> never make progress and requires human intervention (killing the process).
> It would be prudent to consider a sweeping improvement in the course of
> fixing this, such as initiating a shutdown on any uncaught exception when
> transitioning in SchedulerLifecycle.
