> Key: HIVE-5038
> URL: https://issues.apache.org/jira/browse/HIVE-5038
> Project: Hive
> Issue Type: Bug
> Components: PTF-Windowing
> Affects Versions: 0.11.0
> Reporter: Barrett Strausser
> Assignee: Edward Capriolo
> Priority: Minor
> Attachments: fake_customer_order_data.csv, rank_semantics_test_data.hive.sql

>
> Issue 1 : The rank operator is sensitive to case.
> The following works :
> SELECT
> fco.cmscustid,fco.orderdate, rank() w
> FROM
> fake_customer_orders fco
> window
> w as (partition by fco.cmscustid order by fco.orderdate)
> While this does not :
> SELECT
> fco.cmscustid,fco.orderdate, RANK() w
> FROM
> fake_customer_orders fco
> window
> w as (partition by fco.cmscustid order by fco.orderdate);
> The failing call returns :
> FAILED: SemanticException Failed to breakup Windowing invocations into Groups. At least 1 group must only depend on input columns. Also check for circular dependencies.
> Underlying error: org.apache.hadoop.hive.ql.exec.UDFArgumentTypeException: One or more arguments are expected.
> Issue 2:
> The following works :
> SELECT
> fco.cmscustid,fco.orderdate, RANK(fco.orderdate) w
> FROM
> fake_customer_orders fco
> window
> w as (partition by fco.cmscustid order by fco.orderdate);
> This does not :
> SELECT
> fco.cmscustid,fco.orderdate, rank(fco.orderdate) w
> FROM
> fake_customer_orders fco
> window
> w as (partition by fco.cmscustid order by fco.orderdate);
> and returns -
> FAILED: SemanticException Failed to breakup Windowing invocations into Groups. At least 1 group must only depend on input columns. Also check for circular dependencies.
> Underlying error: Ranking Functions can take no arguments
> This has been reproduced by mutliple users and probably pertains to other PTF/windowing functions as well although I haven't duplicated them
> In no case is the returned output the expected output. I'll file another jira for this.
