I've been struggling through setting up a spark/hadoop/EMR driven set up. It's all out of AWS. I think I've got it right but one thing that has stumped me is what to put in for the login info when using the spark connector:
What usernames and passwords should be put in for the Authentication line? I've created a lot in the process but keep timing out.
How do you log in to the database directly? Are you the admin on the database?
