------------------------------------
Summary: RowTypeInfo equality should not depend on field names
Key: FLINK-3792
URL: https://issues.apache.org/jira/browse/FLINK-3792
Project: Flink
Issue Type: Bug
Components: Table API
Affects Versions: 1.1.0
Reporter: Vasia Kalavri
Currently, two Rows with the same field types but different field names are not
considered equal by the Table API and SQL. This behavior might create problems,
e.g. it makes the following union query fail:
{code}
SELECT STREAM a, b, c FROM T1 UNION ALL
(SELECT STREAM d, e, f FROM T2 WHERE d < 3)
{code}
where a, b, c and d, e, f are fields of corresponding types.
{code}
Cannot union streams of different types: org.apache.flink.api.table.Row(a:
Integer, b: Long, c: String) and org.apache.flink.api.table.Row(d: Integer, e:
Long, f: String)
{code}
