> Key: HIVE-23858
> URL: https://issues.apache.org/jira/browse/HIVE-23858
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2
> Reporter: Adesh Kumar Rao
> Assignee: Adesh Kumar Rao
> Priority: Minor
>
> When multiple HS2's are running and a function is registered on one of them, we need to connect to each of remaining HS2's explicitly and run reload-functions command.
>
> Without doing reload-function, if we try using the function in any of the remaining HS2's, the command will fail saying invalid function.
>
> The idea here is to check for function existence, not only in functionRegistry but also from metastore if the function does not exists in registry.
