> Duplicate String.format in YarnOutputFiles.getSpillFileForWrite
> ---------------------------------------------------------------
>
> Key: MAPREDUCE-5708
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5708
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Konstantin Weitz
> Assignee: Konstantin Weitz
> Priority: Minor
> Fix For: 2.8.0
>
> Attachments: 0001-Removed-duplicate-String.format.patch
>
> Original Estimate: 10m
> Remaining Estimate: 10m
>
> The code responsible for formatting the spill file name (namely
> _getSpillFileForWrite_) unnecessarily calls _String.format_ twice. This does
> not only affect performance, but leads to the weird requirement that task
> attempt ids cannot contain _%_ characters (because these would be interpreted
> as format specifiers in the outside _String.format_ call).
> I assume this was done by mistake, as it could only be useful if task attempt
> ids contained _%n_.
