    Description

      Looks like the following logic kicks in during OpTraitsRulesProcFactory.TableScanRule.checkBucketedTable(), which prevents the table from being considered a proper bucketed table:
      // The number of files for the table should be same as number of
      // buckets.
      if (fileNames.size() != 0 && fileNames.size() != numBuckets)

      { return false; }
