> create table test (
> col1 int,
> `col 2` int check (`col 2` > 10) enable novalidate rely,
> constraint check_constraint check (col1 + `col 2` > 15) enable novalidate
> rely

> {code}
> It fails with:
>
> {code:java}
> org.apache.hadoop.hive.ql.parse.SemanticException: Invalid Constraint syntax
> Invalid CHECK constraint expression: col 2 > 10.
