> Currently, adding a temporary UDF and calling LLAP with it (bypassing the LlapDecider
check, I did it by just modifying the source) only fails because the class could not be found.
If the UDF was accessible to LLAP, it would execute. Inside the daemon, UDF instantiation
should fail for custom UDFs (and only succeed for whitelisted custom UDFs, once that is implemented).
