Thejas M Nair commented on PIG-2168:
------------------------------------
Patch looks good. A minor comment - Lists.newArrayListWithCapacity would be a
better for this case, than Lists.newArrayListWithExpectedSize.
Lists.newArrayListWithExpectedSize adds padding, which is unnecessary in this
case.

> A prerequisite for a naive cubing implementation:
> A UDF that, given a set of dimensions (a, b, c) generates all the points on
> the cube:
> (a, b, c), (a, b, null), (a, null, c), (null, b, c), (null, null, c), (a,
> null, null), (null, b, null), (null, null, null).
