I'm afraid not. protobuf maybe compatible at the wire level -the marshalled data is good-, but the generated classes in jars Will not link to any version other than that they were explicitly compiled with. this is why hadoop 3.3 has a private shaded copy in the hadoop-thirdparty JAR -how to stop the Hadoop/hdfs code restricting what others can use.
