> 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.
