luoyuxia updated FLINK-27603:
-----------------------------
Description:
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 exception for the statement
"reload function".
I'm wondering keep the current behavior to throw excpetion or consider it as an
'NopOperation'.
