I have no clue why but after installing hortonworks so I could investigate radoop, my credentials from my server no longer work. It seems like something altered my mySQL settings, even if there should be no relation at all.
Is there a way to reset the password back to the original 'changeit' entry, or would I be forced to completely reinstall everything ?
nevermind, seems part of mySQL was locked and I was able to get it running again. The error message was just a bit confusing...
