> Currently in the RelToSqlConverter class, there is no visit method to handle the Sample RelNode.If a SQL plan has Sample RelNode, RelToSqlConverter will throw a AssertionError like this:
> {code:java}
>  java.lang.AssertionError: Need to implement org.apache.calcite.rel.core.Sample
> {code}
> This will cause the Sample RelNode plan to fail to translate to the corresponding dialect.
