> In SortValidator, Maps invoke the method called deduceInputFile in the
> configure method. The deduceInputFile is supposed to return whether the input
> file belongs to the sort-input directory or the sort-output directory.
> However, the check that deduceInputFile does -
> inputFile.toString().startsWith(inputPaths[0].toString()) - is not totally
> correct. The check will always returns true for inputPaths like
> /user/foo/smallInput/<filenames>, /user/foo/smallInput-sorted/<filenames>.
> This finally causes the SortValidator to declare the sort output as incorrect.
