Wes McKinney commented on ARROW-2708:
-------------------------------------

hi [~ghatageanup] the mailing thread referenced is here: 
https://lists.apache.org/thread.html/da5ee8247dcb209ac39c9e8f147c945304d1714ee377e0f7708162b3@%3Cdev.arrow.apache.org%3E

I don't think you want to use {{ARROW_CHECK}}, but returning {{nullptr}} when 
the buffer is null (or has a nullptr inside) is the right solution

> [C++] Internal GetValues function in arrow::compute should check for nullptr
