All Implemented Interfaces:

Task

public static enum Task.TrackingState extends Enum<Task.TrackingState>
Tracking plugin state. A task can be untracked, or moves though states
NEW --> START_ACK --> END_ACK

Tracking state is separate from, but integrated with, task state. This is because, due to latency, tracking events may be slightly out of sync with YARN events.
