             Summary: Ozone: Compile Ozone/HDFS/Cblock protobuf files with proto3 compiler using maven protoc plugin
                 Key: HDFS-13389
                 URL: https://issues.apache.org/jira/browse/HDFS-13389
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh
             Fix For: HDFS-7240


Currently all the Ozone/HDFS/Cblock proto files are compiled using proto 2.5, this can be changed to use proto3 compiler.

This change will help in performance improvement as well because currently in the client path, the xceiver client ratis converts proto2 classes to proto3 using byte string manipulation.

Please note that for rest of hadoop (except Ozone/Cblock/HDSL), the protoc version will still remain 2.5 as this proto compilation will be done through the following plugin.
