Can I ask, do you really need Hadoop and "big data" for this? There have gotta be substantially fewer than 10k courts in the United States. What needs processed that SQL can't accommodate?
Meta-note: It may be wise to make a rule on what's appropriate to leave as a comment on these hiring posts. I can see some companies shying away if they feel like it's going to turn into a "critique my stack and/or hiring process" thing.
