Summary: Stack overflow error thrown when running join query
Key: CALCITE-3479
URL: https://issues.apache.org/jira/browse/CALCITE-3479
Project: Calcite
Issue Type: Bug
Reporter: Amit Chavan
A unit test in our project is failing which is as below.
The query in question is
"SELECT * FROM tblspace1.t1 t10, tblspace1.t2 t20 WHERE t20.n1 = 3 AND t10.n1 =
3 AND t20.n1 = t10.n1"
I get a stack overflow error-
