Eric Lin updated HIVE-12368:
----------------------------
Priority: Minor (was: Major)
> Provide support for different versions of same JAR files for loading UDFs
> -------------------------------------------------------------------------
>
> Key: HIVE-12368
> URL: https://issues.apache.org/jira/browse/HIVE-12368
> Project: Hive
> Issue Type: New Feature
> Components: HiveServer2
> Reporter: Eric Lin
> Assignee: Vaibhav Gumashta
> 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
> environment will 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
