How to implement Hadoop as non map/reduce ?

We are bachelor students working on programming project. We need to use Hadoop and Java.

Our application loads a FASTQ document, counts IDs, read length, count all bases, perfoms k-mer analysis. We implemented it as a Map/Reduce Approach. Now, my question is how to use Hadoop in a non map/reduce manner?

Is it enough to just block reducers,

 job.setNumreduceTasks(0)

Or another way also exists?

I do not quite understand the intention behind this question. If the main function of Hadoop is to provide a map/reduce framework, why would you then turn this function off? Just for comparing run-time or testing?

Yes, just for testing, as a second task in our Project.
