> Key: SPARK-16771
> URL: https://issues.apache.org/jira/browse/SPARK-16771
> Project: Spark
> Issue Type: Bug
> Affects Versions: 1.6.2, 2.0.0
> 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:
> {code}
> java.lang.StackOverflowError
