Enum Task.TrackingState

java.lang.Object

java.lang.Enum<Task.TrackingState>

org.apache.drill.yarn.appMaster.Task.TrackingState

All Implemented Interfaces:

Serializable, Comparable<Task.TrackingState>

Enclosing class:

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.
