> Issue Type: Bug
> Components: Scheduler

> We have observed the scheduler attempting to kill tasks before
> {{registered()}} had been called. This resulted in the driver dropping those
> attempts on the floor. Since the driver didn't signal failure to the
> scheduler (but instead logged an error) the scheduler wrote a KILLING state
> transition to the replicated log and signaled success to the client. Since
> the {{killTasks}} message was never sent the task timed out and the task
> continued to run until the GC executor reconciled state.
