Add Backticks to Table References

CDP includes the Hive-16907 bug fix, which rejects `db.table` in SQL queries. A dot (.) is not allowed in table names. You need to change queries that use such references to prevent Hive from interpreting the entire db.table string as the table name.

Find a table having the problematic table reference.
```
math.students
```
appears in a CREATE TABLE statement.

Enclose the database name and the table name in backticks.


 CREATE TABLE `math`.`students` (name VARCHAR(64), age INT, gpa DECIMAL(3,2));
