[jira] Updated: (HADOOP-92) Error Reporting/logging in MapReduce

     [ http://issues.apache.org/jira/browse/HADOOP-92?page=all ]

Mahadev konar updated HADOOP-92:
--------------------------------

    Attachment: interface.patch

here is patch that reports the machine on which a specific task failed. Clicking on the jobid takes you to a page where  the information is displayed as before (with a little more parsing). But each of the task's is made clickable to show all the attempts that were made to execute this task. On clikcing on this task, you can see the machine on which a particular task attempt was executed and what the error was.

> 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.
