create table t1(id int);

create table t3 as select t1.id, t2.id from t1 join t2;

CBO fails if "hive.stats.column.autogather=true" with "SemanticException Ambiguous column reference: id" & CTAS passes with following table schema
{code:java}
desc t3;

| t1.id     | int        |          |
| t2.id     | int        |          |
+-----------+------------+----------+{code}
create table t3(`t1.id` int, `t2.id` int); will fail for dot(.) in column name.
