> In popular DBMS like MySQL/PostgreSQL/Oracle, runtime exceptions are thrown
> on casting, e.g. cast('abc' as boolean)
> While in Spark, the result is converted as null silently. It is by design
> since we don't want a long-running job aborted by some casting failure. But
> there are scenarios that users want to make sure all the data conversion are
> correct, like the way they use MySQL/PostgreSQL/Oracle.
