ATTACHMENT ID: 12851664 - PreCommit-HIVE-Build
> Hive should raise SemanticException when LPAD/RPAD pad character's length is 0
> ------------------------------------------------------------------------------

> Key: HIVE-15792
> URL: https://issues.apache.org/jira/browse/HIVE-15792
> Project: Hive
> Issue Type: Improvement
> Reporter: Zoltan Chovan
> Assignee: Nandakumar
> Priority: Minor
> Attachments: HIVE-15792.000.patch, HIVE-15792.001.patch
>
>
> For example SELECT LPAD('A', 2, ''); will cause an infinite loop and the
> running query will hang without any error.
> It would be great if this could be prevented by checking the pad character's
> length and if it's 0 then throw a SemanticException.
