>                 URL: https://issues.apache.org/jira/browse/HIVE-12368
>             Project: Hive
>          Issue Type: New Feature
>          Components: HiveServer2
>            Reporter: Eric Lin
>            Priority: Minor

> If we want to setup one cluster to support multiple environments, namely DEV, QA, PRE-PROD etc, this is done in the way that data from different environments can be generated into different locations in the HDFS and Hive Databases.
> This works fine, however, when need to deploy UDF classes for different environments, it becomes tricky, as each class has the same namespace, even though we have created udf-dev.jar, udf-qa.jar etc.
> Creating each HS2 per environment is another option, however, with LB setup, it becomes harder.
> The request is to have HS2 support loading UDFs in such environment, the implementation is open to discussion.
> I know that this setup is no ideal, as the better approach is to have one cluster per environment, however, in the case that you have limited number of nodes in the setup, this might be the only option and I believe many people can benefit from it.
> Thanks
