Robert Hou commented on DRILL-5478:
-----------------------------------
We should still test it on behalf of Support. We don't have to test it
extensively, but ensure it still works in general.
The file size in this example is 256 MB. The memory is 1 GB. Is this a
reasonable set of values?
> Spill file size parameter is not honored by the managed external sort
