> If a user submits a topology with a config that does not match its schema (e.g., String "2" vs Number 2), nimbus will accept the topology but can fail with ClassCastException when it attempts to access the config.
> The exception to this is when the config is read from a file on the client side.  In that case the configuration is validated.  But if the configuration is set in the code or passed on the command line with -c, it will not be validated.
> We should validate the configurations in nimbus when the topology is submitted.
