ATTACHMENT ID: 12709403 - PreCommit-HIVE-TRUNK-Build
> Large IN() clauses: deep hashCode performance during optimizer pass
> -------------------------------------------------------------------
>
> Key: HIVE-10215
> URL: https://issues.apache.org/jira/browse/HIVE-10215
> Project: Hive
> Issue Type: Bug
> Components: Logical Optimizer
> Affects Versions: 1.2.0
> Reporter: Gopal V
> Assignee: Gopal V
> Priority: Minor
> Attachments: HIVE-10215.1.patch
>
>
> The logical optimizer uses several maps and sets, which are exceeding
> expensive for large IN() clauses due to the fact that several part of the
> queries walk over the lists without short-circuiting during hashCode(), while
> equals() is faster due to short-circuiting via less expensive operators.
