Furcy Pin created SPARK-16771:
---------------------------------
Summary: Infinite recursion loop in
org.apache.spark.sql.catalyst.trees.TreeNode when table name collides.
Key: SPARK-16771
URL: https://issues.apache.org/jira/browse/SPARK-16771
Project: Spark
Issue Type: Bug
Affects Versions: 2.0.0, 1.6.2
Reporter: Furcy Pin
How to reproduce:
In spark-sql on Hive
{code}
DROP TABLE IF EXISTS t1 ;
CREATE TABLE test.t1(col1 string) ;
WITH t1 AS (
SELECT col1
FROM t1
)
SELECT col1
FROM t1
LIMIT 2
;
{code}
This make a nice StackOverflowError:

This does not happen if I change the name of the CTE.
I guess Catalyst get caught in an infinite recursion loop because the CTE and
the source table have the same name.
