Pravin Sinha commented on HIVE-27169: ------------------------------------- Merged to the master. Thanks for the patch [~Aggarwal_Raghav] and review [~okumin] !! > 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 > Priority: Minor > Labels: pull-request-available > Time Spent: 1h > Remaining Estimate: 0h > > _*AIM*_ > Create a new locked list called _*hive.conf.locked.list*_ which contains > comma separated configuration that can't be changed during runtime. If > someone try to change them at runtime then it will give WARN log on beeline > itself and will not change that config. > > _*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. > This will be very helpful when organisations are migrating from Hive 1.x, > Hive2.x to higher version and admin want to enforce some configuration which > should remain constant. > > -- This message was sent by Atlassian Jira (v8.20.10#820010)
