Subject [jira] Commented: (MAPREDUCE-1720) 'Killed' jobs and 'Failed' jobs should be displayed seperately in JobTracker UI
Date Mon, 03 Jan 2011 09:07:46 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12976656#action_12976656
] 

Harsh J Chouraria commented on MAPREDUCE-1720:
----------------------------------------------

I think that's a good idea. Jobs can be killed for a reason (say, hadoop job -kill JobID <reason
why we're killing it>?), which can be included into the JobStatus data, same with the whois
of the killer; but when it comes to failure, how do we deduce the 'reason' of failure -- just
task numbers as explained in the MAPREDUCE-343 ticket?

I also think that for Unsuccessful Jobs, displaying map and reduce progress percentages is
not a good thing, as it is not very indicative of the actual progress (Always shows 100 or
0). We could remove this and claim some good real estate to display reasons (limited characters
of it).

> The JobTracker UI shows both Failed/Killed Jobs as Failed. The Killed job status has
been separated from Failed as part of HADOOP-3924, so the UI needs to be updated to reflect
the same.
