Sameer Paranjpye updated HADOOP-544:
------------------------------------
Component/s: mapred
> Replace the job, tip and task ids with objects.
> -----------------------------------------------
>
> Key: HADOOP-544
> URL: http://issues.apache.org/jira/browse/HADOOP-544
> Project: Hadoop
> Issue Type: Improvement
> Components: mapred
> Affects Versions: 0.6.2
> Reporter: Owen O'Malley
> Assigned To: Owen O'Malley
>
> I think that it is silly to have tools parsing the strings that the framework
> builds for task ids. I propose:
> class JobId implements Writable {
> private int;
> ...
> }
> class TaskId extends JobId {
> private boolean isMap;
> private int taskId;
> ...
> }
> class TaskAttemptId extends TaskId {
> private int attemptId;
> ...
> }
> each of the classes will have a toString() method that generates the current
> string.
