ATTACHMENT ID: 12930659 - PreCommit-HIVE-Build
> OpTraits : Select Optraits should stop when a mismatch is detected
> ------------------------------------------------------------------
>
> Key: HIVE-20100
> URL: https://issues.apache.org/jira/browse/HIVE-20100
> Project: Hive
> Issue Type: Bug
> Reporter: Deepak Jaiswal
> Assignee: Deepak Jaiswal
> Priority: Major
> Attachments: HIVE-20100.1.patch, HIVE-20100.2.patch,
> HIVE-20100.3.patch, HIVE-20100.4.patch, HIVE-20100.5.patch
>
>
> The select operator's optraits logic as stated in the comment is,
> // For bucket columns
> // If all the columns match to the parent, put them in the bucket cols
> // else, add empty list.
> // For sort columns
> // Keep the subset of all the columns as long as order is maintained.
>
> However, this is not happening due to a bug. The bool found is never reset,
> so if a single match is found, the value remains true and allows the optraits
> get populated with partial list of columns for bucket col which is incorrect.
> This may lead to creation of SMB join which should not happen.
