> Key: HIVE-14437
> URL: https://issues.apache.org/jira/browse/HIVE-14437
> Project: Hive
> Issue Type: Improvement
> Components: Vectorization
> Affects Versions: 2.2.0
> Reporter: Gopal V
> Assignee: Gopal V
> Attachments: HIVE-14437.1.patch

>
> Currently, the lookup in VectorMapJoinFastBytesHashTable proceeds until the
> max number of metric put conflicts have been reached.
> This can have a fast-exit when encountering the first empty slot during the
> probe, to speed up looking for non-existent keys.
