Fix For: 3.2.3
When I run sql
{code:java}
scala> spark.sql("SELECT 1 UNION SELECT 1;") {code}
I get ParseException:
{code:java}
org.apache.spark.sql.catalyst.parser.ParseException:
mismatched input 'SELECT' expecting {<EOF>, ';'}(line 1, pos 15)== SQL ==
SELECT 1 UNION SELECT 1;

{code}
If I run with parentheses , it works well
{code:java}
scala> spark.sql("(SELECT 1) UNION (SELECT 1);")
res4: org.apache.spark.sql.DataFrame = [1: int]{code}
This should be a bug
