> Pointed out by [~zjshen] in MAPREDUCE-4942.
> In {{o.a.h.mapreduce.Job}} class, the following changed from Hadoop 1 to Hadoop 2.
> boolean failTask(TaskAttemptID): Change in return type from void to boolean.
> boolean killTask(TaskAttemptID): Change in return type from void to boolean.
> TaskCompletionEvent[] getTaskCompletionEvents(int): Change in return type from org.apache.hadoop.mapred.TaskCompletionEvent[]
to org.apache.hadoop.mapreduce.TaskCompletionEvent[].
> Using same rational as in other JIRAs, we should fix this to ensure Hadoop 1 to Hadoop
2 source compatibility (taking 0.23.x releases as a casualty as there is not right way for
everybody because we screwed up :( ). Flagging it as incompatible change because of 0.23.
