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
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.
