Vihang Karajgaonkar commented on HIVE-17167:
--------------------------------------------

Yes, without sub-classing I agree we cannot enforce this in code. Given that 
users can still do a conf.get("key") instead of MetastoreConf.getX(conf, key), 
adding a check for inconsistent values in MetastoreConf.getX() may not work for 
all the cases and will only add to the confusion.

> Create metastore specific configuration tool

> As part of making the metastore a separately releasable module we need 
> configuration tools that are specific to that module.  It cannot use or 
> extend HiveConf as that is in hive common.  But it must take a HiveConf 
> object and be able to operate on it.
> The best way to achieve this is using Hadoop's Configuration object (which 
> HiveConf extends) together with enums and static methods.
