Running custom jar file with input parameters on Amazon EMR

So, I am trying to run the WordCount hadoop application on Amazon EMR. I have my own data file which I uploaded to abc bucket. I also added the wordcount.jar file under abc bucket. Can anyone tell me when I create the cluster, how can we give the path to the data file and also do we need to give the output directory path as well and if yes then how can I give the output directory path?
