Priyo Mustafi commented on MAPREDUCE-1915: ------------------------------------------ Hi Rares, The fix makes sense. I am writing a testcase for it but then I am not sure when this scenario is going to ever occur. Looks like you noticed an OutOfBoundException but under what circumstance? > IndexCache - getIndexInformation - check reduce index Out Of Bounds > ------------------------------------------------------------------- > > Key: MAPREDUCE-1915 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1915 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: tasktracker > Affects Versions: 0.20.1, 0.20.2, 0.20.3, 0.21.0, 0.22.0 > Reporter: Rares Vernica > Priority: Trivial > Attachments: MAPREDUCE-1915.patch > > > When checking if the "reduce" index is out of bounds the check should be > info.mapSpillRecord.size() <= reduce > instead of: > info.mapSpillRecord.size() < reduce > Not a big bug since an Out Of Bounds is thrown downstream anyway. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
