Scott Chen updated MAPREDUCE-1829: ---------------------------------- Attachment: (was: MAPREDUCE-1829.txt) > JobInProgress.findSpeculativeTask should use min() to find the candidate > instead of sort() > ------------------------------------------------------------------------------------------ > > Key: MAPREDUCE-1829 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1829 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: jobtracker > Affects Versions: 0.22.0 > Reporter: Scott Chen > Assignee: Scott Chen > Priority: Minor > Fix For: 0.22.0 > > > findSpeculativeTask needs only one candidate to speculate so it does not need > to sort the whole list. It may looks OK but someone can still submit big jobs > with small slow task thresholds. In this case, this sorting becomes expensive. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
