> Key: MAPREDUCE-5531
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5531
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv1, mrv2
> Affects Versions: 2.1.1-beta
> Reporter: Robert Kanter

> {{mapreduce.TaskID}} in branch-1 has these two constructors:
> {code:java}
> public TaskID(JobID jobId, boolean isMap, int id)
> public TaskID(String jtIdentifier, int jobId, boolean isMap, int id)
> {code}
> In branch-2, {{mapreduce.TaskID}} no longer has either of the above two
> constructors.
> Also, {{mapreduce.TaskAttemptID}} in branch-1 has this constructor:
> {code:java}
> public TaskAttemptID(String jtIdentifier, int jobId, boolean isMap, int
> taskId, int id)
> {code}
> In branch-2, {{mapreduce.TaskAttemptID}} no longer his this constructor.
> It looks like these constructors were probably removed because the {{boolean
> isMap}} was replaced by an enum, {{TaskType}}.
> This means that any code that tries to use any of those constructors will not
> be binary or source compatible (in fact, the missing {{TaskAttemptID}}
> constructor calls one of the missing {{TaskID}} constructors).
