Using EMRFS to store the outputs in S3 is definitely the way to go. I mean, who wants to be the one to tell the boss they used the 's3n' URI? That's like pulling a Betamax in the age of Netflix.

Loading the data into HDFS and then writing the final output to S3 seems like overkill for this use case, where we don't need to retain the intermediate data.

Defining the ETL steps as separate AWS Data Pipeline activities could work, but it might add unnecessary complexity compared to the EMRFS approach.

That's a valid point, but I still think storing outputs in S3 using EMRFS is more efficient.

I'm not sure s3n URI is the right choice here, as it doesn't seem to address the requirement of not retaining the data locally.

I disagree, I believe option D is better because it involves loading data into HDFS first.
