Review comment:
This was to suppress javac warnings due to usage of
{{ProtobufRpcEngine}} in {{ProtobufRpcEngine2}}. I have moved to new method,
where this exact usage is present.

> Changing from Protobuf 2 to Protobuf 3 broke some stuff in Apache Hive
> project. This was not an awesome thing to do between minor versions in
> regards to backwards compatibility for downstream projects.
> Additionally, these two frameworks are not drop-in replacements, they have
> some differences. Also, Protobuf 2 is not deprecated or anything so let us
> have both protocols available at the same time. In Hadoop 4.x Protobuf 2
> support can be dropped.
