Thanks for raising this issue. I also ran into this while making a

Hello Gang,
I'm trying to upgrade the Apache Hive project to use Hadoop 3.3.0 so that
Hive can build/run with JDK 9/11. The current Hadoop dependency for Hive
fails to run with JDK 9/11.
However, I ran into an issue:
ProtobufRpcEngine2
It looks like Hadoop commons updated the PB RPC Engine fro
Alternatively, does anyone know how it was done that made the code

instead of it's own? I can perhaps regenerate the Hive code with the
Hadoop 3P libraries and that might fix it.

mechanism. However, tests are failing for Hive complaining about:
"ReRegistration of rpcKind"
I believe this is because both classes register, sta
