I would flag it for migration to StackOverflow or even ServerFault. Your question deals more with Hadoop than it does with OS X and Hadoop is way out of scope for this site. There are very little developer service experts viewing questions here.
To your voting question: we suffer from poor voting participation on this site. It's a long-standing issue we've been trying to solve by promoting voting behaviour and such through commenting on posts and in the chat channel. But we deal with higher number of "passerby" type users here because of our subject nature. Casual computer users are more common here than on a site like StackOverflow or ServerFault.
As for visibility: you can always attach a bounty to the question to make it more visible. I find letting people know about it in the chat channel can help too. Though even the chat channel isn't as active as it is some place like StackOverflow.
