[jira] [Created] (HIVE-5038) rank operator is case-sensitive and
has odd semantics
Barrett Strausser created HIVE-5038:
---------------------------------------
Summary: rank operator is case-sensitive and has odd semantics
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
Priority: Minor
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.
