Ashutosh Chauhan commented on HIVE-4171:
----------------------------------------

I agree with [~prasadm] that HiveConf is not ideal to store this info. 
SessionState is the right place to store it. Further, adding restrictList in 
HiveConf for plugging security backdoor resulting from it is less than ideal. 
[~thejas] It seems you agreed too, but found storing in HiveConf is easier 
implementation-wise. Is that correct? It will be good to figure out what are 
challenges in storing in SessionState.

> metastore.Hive is thread local instance, which can have different status with 
> SessionState. Currently the only status in metastore.Hive is database name in 
> use.
