             Summary: New Locked List to prevent configuration change at runtime without throwing error
                 Key: HIVE-27169
                 URL: https://issues.apache.org/jira/browse/HIVE-27169
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 4.0.0-alpha-2
            Reporter: Raghav Aggarwal
            Assignee: Raghav Aggarwal


_*AIM*_

Create a new locked list called{{ hive.conf.locked.list}} which contains comma separated configuration that won't be changed during runtime. If someone try to change them at runtime then it will give WARN log on beeline itself.

 

_*How is it different from Restricted List?*_

When running hql file or at runtime, if a configuration present in restricted list get updated then it will throw error and won't proceed with further execution of hql file.

With locked list, the configuration that is getting updated will throw WARN log on beeline and will continue to execute the hql file.

 

_*Why is it required?*_

In organisations, admin want to enforce some configs which user shouldn't be able to change at runtime and it shouldn't affect user's existing hql scripts. Therefore, this locked list will be useful as it will not allow user to change the value of particular configs and it will also not stop the execution of hql scripts.

 

{_}*NOTE*{_}: Only at cluster level {{hive.conf.locked.list }}can be set and after that the hive service needs to be restarted.
