> In Hive, by "reload function", the user can use the function defined in other session.
> But in flink, it will always get the function from the catalog, and if it's hive catalog, it'll load all the user defined functions from the metastore.
> So, there's no need to "reload function" explicitly for it actually is done implicitly.
> But when use Hive dialect in Flink, it'll throw an unsupported exception for  the statement  "reload function".
> I'm wondering keep the current behavior to throw excpetion or consider it as an 'NopOperation'.
