             Summary: LaunchException needs transient task timeout for reschedule
                 Key: AURORA-1965
                 URL: https://issues.apache.org/jira/browse/AURORA-1965
             Project: Aurora
          Issue Type: Bug
            Reporter: Santhosh Kumar Shanmugham


In {{TaskAssignerImpl}} a {{LaunchException}} either due to race-condition for grabbing {{Offer}} or Scheduler Driver {{acceptOffers}} failure will result in the task being help up in {{ASSIGNED}} state, until transient task timeout kicks in to move the task to LOST, resulting in a reschedule.

[https://github.com/apache/aurora/blob/dbe71374399d86d77baa35efbeca4fffa34f380e/src/main/java/org/apache/aurora/scheduler/scheduling/TaskAssignerImpl.java#L135]

The impact of this is minimal due to fact that multiple conditions need to align for this situation to happen.

This happens since the call to {{changeState}} fails since the supplied current state (PENDING) in the method call is different from the actual state of the task (ASSIGNED).
