Furcy Pin created SPARK-17296:
---------------------------------
Summary: Spark SQL: cross join + two joins = BUG
Key: SPARK-17296
URL: https://issues.apache.org/jira/browse/SPARK-17296
Project: Spark
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Furcy Pin
In spark shell :
{code}
CREATE TABLE test (col INT) ;
INSERT OVERWRITE TABLE test VALUES (1), (2) ;
SELECT
COUNT(1)
FROM test T1
CROSS JOIN test T2
JOIN test T3
ON T3.col = T1.col
JOIN test T4
ON T4.col = T1.col
;
{code}
returns :
{code}
Error in query: cannot resolve '`T1.col`' given input columns: [col, col]; line
6 pos 12
{code}
Apparently, this example is minimal (removing the CROSS or one of the JOIN
causes no issue).
