HAWQ-999. Treat hash table as random when file count is not in proporâ¦
â¦tion 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.
