Review Comment:
   Per above, it didn't work for me the first time I tried and it was giving me 
error related the architecture.  Fortunately, I pasted the error in the Slack 
thread:
   
   ```
   
ozone/hadoop-hdds/interface-client/target/protoc-plugins/protoc-gen-grpc-java-1.71.0-osx-aarch_64.exe:
 program not found or is not executable
   Please specify a program using absolute path or make sure the program is 
available in your PATH system variable
   --grpc-java_out: protoc-gen-grpc-java: Plugin failed with status code 1.
   ```
   
   Not sure if something was changed since the first time I tried it, but I 
didn't have that problem today.
