---------------------------------

             Summary: Treat hash table as random when file count is not in proportion to bucket
number of table.
                 Key: HAWQ-999
                 URL: https://issues.apache.org/jira/browse/HAWQ-999
             Project: Apache HAWQ
          Issue Type: Improvement
          Components: Core
            Reporter: Hubert Zhang
            Assignee: Lei Chang


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.
