Doug Cutting resolved HADOOP-92:
--------------------------------
Fix Version: 0.2
Resolution: Fixed
Assign To: Mahadev konar
This mostly looks good. I committed it with the following changes:
1. TaskStatus is not a public class, so a public method in another public class
should not return it. For now, I just made the method package-private, since
the jsp pages are compiled in the same package. Longer-term we should probably
copy this information into the TaskReport, the public version of a TaskStatus,
or something. This information should be available to other applications
through a public API, and through an RPC in the JobSubmissionProtocol.
2. I renamed JobTracker.getallTaskStatus to be getTaskStatuses, like the
JobInProgress method, and also using correct camel-case.
3. Rather than add a new TaskStatus contructor, leaving an old one that is no
longer called, I removed the old one. We don't need dead code around. This is
package-private, so we can be sure that no code outside of this package uses
the old constructor.
4. The patch removed some inter-method whitespace. I restored it.

> Currently Mapreduce does not tell you which machine failed to execute the
> task. Also, it would be nice to have features wherein there is a log report
> with each job, saying the number of tasks it ran (reporting which one failed
> and on which machine, listing any error information it can) with the
> start/end/execute time of each task.
