I find a lot of the use cases end up using hadoop anyway and I was wondering why tools like oozie are not used. It appears as if such projects are feats of engineering and nothing more. I might be gravely mistaken but that&#x27;s how I see. Comments that suggest otherwise would be greatly appreciated. EDIT: I also find it odd that one might write a workflow manager because they can&#x27;t find an equivalent one for python.
