枚举 QueueProcessingStatistics.State

java.lang.Object

java.lang.Enum<QueueProcessingStatistics.State>

org.apache.hadoop.util.QueueProcessingStatistics.State

所有已实现的接口:

Serializable, Comparable<QueueProcessingStatistics.State>

封闭类:

QueueProcessingStatistics

public static enum QueueProcessingStatistics.State
extends Enum<QueueProcessingStatistics.State>

This enum provides the "states" of a state machine for QueueProcessingStatistics. The meanings of the states are:

• BEGIN_COLLECTING - Ready to begin.
• IN_FIRST_CYCLE - Started the first cycle.
• IN_SOLE_CYCLE - Still in first cycle, but already know there will be no further cycles because this one will complete all needed work. When done, will go straight to "DONE_COLLECTING".
• DONE_FIRST_CYCLE - Done first cycle, doing subsequent cycles.
• IN_LAST_CYCLE - Started the last cycle.
• DONE_COLLECTING - Done with last cycle, finishing up.
