Description

TSQL prints a wrong error message related `InPredicate` when EXISTS clause is used like following statement.

—
default> select * from t1 where exists (select * from t1);
ERROR: Can not set boolean field org.apache.tajo.algebra.InPredicate.not to org.apache.tajo.algebra.ExistsPredicate
—

It should be like the following.
—
default> select * from t1 where exists (select * from t1);
select * from t1 where exists (select * from t1);
ERROR: Cannot support EXISTS clause yet
