When looking at this question I see that it should probably be closed. It's written as an XY question (mongoDB vs. hadoop) when what he really wants to know (but doesn't know it yet) is how to use mongoDB and hadoop together to solve his problem. Do I:
- flag the question as inappropriate
- tell him to close it and open a new question (and give him the wording to use), or
- Just edit his question and completely change it to the question he's really getting at
- Just ignore his question and tell him what he needs to know
My problem is that I'm not a mongoDB expert and so I can't do (4) and even if I did, someone will probably flag the question as being inappropriate anyway.
So what's the right thing to do here?
