> When user performs add/remove column in DDL, Spark will get the old/wrong
> schema.
>
> Analyse
> Currently Spark data frame API relies on QueryEntity to construct schema, but
> QueryEntity in QuerySchema is a local copy of the original QueryEntity, so
> the original QueryEntity is not updated when modification happens.
>
> Solution
> Use GridQueryTypeDescriptor to replace QueryEntity
