> The udfs like reflect() or java_method() enables executing a java method as 
> udf. While this offers lot of flexibility in the standalone mode, it can 
> become a security loophole in a secure multiuser environment. For example, in 
>  HiveServer2 one can execute any available java code with user hive's 
> credentials.
> We need a whitelist and blacklist to restrict builtin udfs in Hiveserver2.
