> Minor issues in array_intersect udf
> -----------------------------------
>
> Key: HIVE-27482
> URL: https://issues.apache.org/jira/browse/HIVE-27482
> Project: Hive
> Issue Type: Sub-task
> Reporter: Taraka Rama Rao Lethavadla
> Assignee: Taraka Rama Rao Lethavadla
> Priority: Minor
> Labels: pull-request-available
>
> 1. SELECT array(1,2,3),array_intersect(array(1, 2, 3),array(1,3,4)); gives
> wrong output
> {noformat}
> [1,3] [1,3]{noformat}
> instead of
> {noformat}
> [1,2,3][1,3]{noformat}
> 2. SELECT array_intersect(array(),array()); should give empty array instead
> of NULL
> 3. Error handling when elements of array are not comparable
> These fixes were already present on array_except udf whose implementation is
> identical to array_intersect, Ref: [https://github.com/apache/hive/pull/4090]
