Hopefully, anyone pondering a new project would investigate Hadoop (or any other tool) before choosing it. Not built for ad hoc queries? Yeah, that's fairly open. Requires programming ability? Well, yes, that's the intent: it's not a studio-type environment. You need staff to keep it running? If you have thousands of nodes and need them, then you probably should already have the resources for an engineer or two. Maybe I'm missing something, but it sounds like the author tried to fit a tool to his needs rather than choosing a tool that already does so.
