unable to create TF-IDF in mahout 0.7



after creating term vectors in from sequence file 



i used below snippet (according to new version)



            TFIDFConverter.processTfIdf(
              new Path(outputDir , DictionaryVectorizer.DOCUMENT_VECTOR_OUTPUT_FOLDER),
              new Path(outputDir), conf,TFIDFConverter.calculateDF(new Path(outputDir,DictionaryVectorizer.DOCUMENT_VECTOR_OUTPUT_FOLDER),new Path(outputDir),conf,chunkSize) ,minDf,
              maxDFPercent, norm, true, sequentialAccessOutput, false, reduceTasks);


But it generates empty tfidf vectors , any clue of how to achieve this in mahout 0.7 using api ?
