    Description

      After upgrade/shade of protobuf to 3.7 version, existing Hadoop-Rpc client-server implementations using ProtobufRpcEngine will not work.

      So, this Jira proposes to keep existing ProtobuRpcEngine as-is (without shading and with protobuf-2.5.0 implementation) to support downstream implementations.

      Use new ProtobufRpcEngine2 to use shaded protobuf classes within Hadoop and later projects who wish to upgrade their protobufs to 3.x.
