-------------------------------------------------
Summary: 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
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]
