> Key: HIVE-21802
> URL: https://issues.apache.org/jira/browse/HIVE-21802
> Project: Hive
> Issue Type: Bug
> Components: Parser, Query Processor
> Reporter: Oleksiy Sayankin
> Assignee: Oleksiy Sayankin
> Priority: Critical
> Attachments: HIVE-21802.1.patch, HIVE-21802.2.patch

> *STEPS TO REPRODUCE:*
> 1. Create a table:
> {code:java}
> CREATE TABLE i (id INT, a1 INT, b1 BOOLEAN);
> {code}
> 2. Run the query which was working in Hive-1.2: ({{ORDER}} clause _before_
> {{WINDOW}})
> {code:java}
> SELECT id
> FROM (
> SELECT
> id,
> a1,
> ROW_NUMBER() OVER w1 AS rn,
> b1
> FROM i a
> ORDER BY id, b1, a1 DESC
> WINDOW w1 as (PARTITION BY id, b1 ORDER BY a1 DESC)
> ) tmp WHERE rn=1 DISTRIBUTE BY id;
> {code}
> *ACTUAL RESULT:*
> The query fails with an exception you can find above.
> The query from Step 2 which works for Hive-2.3 is ( ({{ORDER}} clause _after_
> {{WINDOW}})):
> {code:java}
> SELECT id
> FROM (
> SELECT
> id,
> a1,
> ROW_NUMBER() OVER w1 AS rn,
> b1
> FROM i a
> WINDOW w1 as (PARTITION BY id, b1 ORDER BY a1 DESC)
> ORDER BY id, b1, a1 DESC
> ) tmp WHERE rn=1 DISTRIBUTE BY id;
> {code}
> Hive-2.3 also fails to parse subquery ( ({{ORDER}} clause _before_
> {{WINDOW}})):
> {code:java}
> SELECT
> id,
> a1,
> ROW_NUMBER() OVER w1 AS rn,
> b1
> FROM i a
> ORDER BY id, b1, a1 DESC
> WINDOW w1 as (PARTITION BY id, b1 ORDER BY a1 DESC)
> {code}
> Customer is facing issue regularly this is occurring after upgrade . the
> workaround given by us need lot of code changes which will get them back to
> squire one they need to follow process and will cost them a lot.
