> Key: HADOOP-17046
> URL: https://issues.apache.org/jira/browse/HADOOP-17046
> Project: Hadoop Common
> Issue Type: Improvement
> Components: rpc-server
> Affects Versions: 3.3.0
> Reporter: Vinayakumar B
> Assignee: Vinayakumar B
> Priority: Major
>
> 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.
