Subject [jira] Updated: (HADOOP-92) Error Reporting/logging in MapReduce
Date Wed, 29 Mar 2006 22:37:53 GMT
     [ 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.
