Alejandro Abdelnur created MAPREDUCE-5304:
---------------------------------------------
Summary: mapreduce.Job killTask/failTask/getTaskCompletionEvents
methods have incompatible signature changes
Key: MAPREDUCE-5304
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5304
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.0.4-alpha
Reporter: Alejandro Abdelnur
Assignee: Karthik Kambatla
Priority: Blocker
Fix For: 2.1.0-beta
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.
