Subject [jira] [Created] (AURORA-45) Scheduler should wait for registered to be called before attempting to invoke driver

---------------------------------

             Summary: Scheduler should wait for registered to be called before attempting
to invoke driver
                 Key: AURORA-45
                 URL: https://issues.apache.org/jira/browse/AURORA-45
             Project: Aurora
          Issue Type: Bug
          Components: Scheduler
            Reporter: Bill Farner
            Assignee: Bill Farner


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.
