Is jar creation necessary to execute MR on a remot

问题:

I have been trying Spring Data for Hadoop to execute a MR job from my local Windows STS on a remote Hadoop cluster.

The issue I face is mentioned in detail here

There's a similar thread that has forced me to ask the below question.

Is it necessary to first create a .jar file on my local windows machine(within the Eclipse/STS project's lib etc.) before it can be executed on a remote Hadoop cluster? Can't Spring Data simply push my code onto the remote cluster and trigger the execution?
