> Hive dialect supports "reload function"
> ---------------------------------------
>
> Key: FLINK-27603
> URL: https://issues.apache.org/jira/browse/FLINK-27603
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Reporter: luoyuxia
> Assignee: luoyuxia
> Priority: Major
> Labels: pull-request-available, stale-assigned
> Fix For: 1.17.0
>
>
> 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'.
