Prasad Mujumdar commented on HIVE-4741:
---------------------------------------

This particular is not directly exposed to end users via SQL or configuration. 
It fixes the way this restrict list configuration can be changed 
programatically from a HiveServer2 session. It's only useful for custom hooks.

> Add Hive config API to modify the restrict list

> HiveConf supports a restrict list configuration which is a black list of 
> configurations that can be modified through the 'set x=y'. This is especially 
> useful for HiveServer2 to restrict clients from overriding some of server 
> configurations.
> Currently the restrict list value can't be changed after the HiveConf object 
> is instantiated. It would be useful for custom code like Hooks to have a way 
> to be able to update that setting.
