Jane Beckman commented on HAWQ-999:
-----------------------------------
Should we note this behavior in the documentation, where we discuss hash tables
and the bucket number?
> Treat hash table as random when file count is not in proportion to bucket
> number of table.

> By definition, file count of a hash table should be equal to or a multiple of
> the bucket number of the table. So if mismatch happens, we should not treat
> it as hash table in data locality algorithm.
