If Cheyenne is talking about the query server, I'm not sure where you're getting that from, Ted. It doesn't directly depend on protobufs, it's pulled in from Avatica:
https://github.com/apache/phoenix/blob/v4.9.0-HBase-1.2/phoenix-queryserver/pom.xml Avatica does use protobuf 3: https://github.com/apache/calcite/blob/calcite-avatica-1.9.0/avatica/pom.xml Cheyenne, could you try building with an earlier version of Avatica?
