Deepak Jaiswal updated HIVE-17939:
----------------------------------
Status: Patch Available (was: In Progress)
> Bucket map join not being selected when bucketed tables is missing bucket
> files
> -------------------------------------------------------------------------------
>
> Key: HIVE-17939
> URL: https://issues.apache.org/jira/browse/HIVE-17939
> Project: Hive
> 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;
> }
