>                 Key: HIVE-23858
>                 URL: https://issues.apache.org/jira/browse/HIVE-23858
>             Project: Hive
>          Issue Type: Improvement
>          Components: HiveServer2, Standalone Metastore
>            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.
