How one can disable a Pig command and operator?

An admin feature provides the ability to blacklist or/and whitelist certain commands and operations that could be not very safe in a multitenant environment.

Blacklisting assigns "pig.blacklist" to a comma-delimited set of operators and commands. For instance, pig.blacklist=rm,killcross would disable users from executing any of "rm", "kill" commands and "cross" operator.

Whitelist disables all commands and operators that are not a safer part of the whitelist environment. For instance, pig.whitelist=load,filter,store will disallow every command and operator other than "load", "filter" and "store".
