> Values that are assigned to configuration parameters of type SYSTEM and
> SESSION must be validated. Currently any value can be assigned to some of the
> SYSTEM/SESSION type parameters.
> Here are two examples where assignment of invalid values to store.format does
> not result in any error.
> {code}
> 0: jdbc:drill:> alter session set `store.format`='1';
> +------------+------------+

> In some cases values to some of the configuration parameters are validated,
> like in this example, where trying to assign an invalid value to parameter
> store.parquet.compression results in an error, which is correct. However,
> this kind of validation is not performed for every configuration parameter of
> SYSTEM/SESSION type. These values that are assigned to parameters must be
> validated, and report errors if incorrect values are assigned by users.
> {code}
> 0: jdbc:drill:> alter session set `store.parquet.compression`='anything';
> Query failed: ExpressionParsingException: Option store.parquet.compression
> must be one of: [snappy, gzip, none]
> Error: exception while executing query: Failure while executing query.
