> Issue Type: Bug
> Reporter: Deepak Jaiswal
> Assignee: Deepak Jaiswal
>
> 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;
> }
