枚举 Pre21JobHistoryConstants.Values

java.lang.Object

java.lang.Enum<Pre21JobHistoryConstants.Values>

org.apache.hadoop.tools.rumen.Pre21JobHistoryConstants.Values

所有已实现的接口:

Serializable, Comparable<Pre21JobHistoryConstants.Values>

封闭类:

Pre21JobHistoryConstants

public static enum Pre21JobHistoryConstants.Values
extends Enum<Pre21JobHistoryConstants.Values>

This enum contains some of the values commonly used by history log events. since values in history can only be strings - Values.name() is used in most places in history file.
