Would anyone here be willing to walk me through setting this stuff up on Amazon Web Services?

I need to run MongoDB on an EC2 instance and connect to an EMR Hadoop cluster for a project, but I have never used any of this stuff (Mongo/Hadoop/the connector/AWS) before so its a bit overwhelming. I have downloaded the connector from Github so far.

I believe I need to run "gradlew jar" to build the jars (not really sure what those do either), but after that I am a bit lost. Have been searching for about a week now, but I cant find a good step-by-step process for this.

Please help..
