> HiveServer2 does not map kerberos name of authenticated principal to local name.
> Due to this, I get error like the following in HiveServer log:
> Failed to validate proxy privilage of knox/hdps.example.com for sam
> I have KINITED as knox/hdps.example.com@EXAMPLE.COM
> I do have the following in core-site.xml
>   <property>
>     <name>hadoop.proxyuser.knox.groups</name>
>     <value>users</value>
>   </property>
>   <property>
>     <name>hadoop.proxyuser.knox.hosts</name>
>     <value>*</value>
>   </property>
