spark scala nlp specialities to optimize my code

Hi,

I wrote a apache spark scala program to find tf-idf using corpus, It's hanging on at point near group by statement. I want someone can fix that issue.

I have list of articles stored in s3 as parquet, so first I'm reading it as dataframe and creating n-grams and keeping it in one hand.

On other hand, s3 has 10k posts (corpus) as parquet. I'm reading it as dataframe and keeping it.

So now I want to find document frequency for each term (n-gram) against corpus
