------------------------------------------

             Summary: Take advantage of protobuf 2.5.0 new features for increased performance
                 Key: HADOOP-9876
                 URL: https://issues.apache.org/jira/browse/HADOOP-9876
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Alejandro Abdelnur


>From protobuf 2.5.0 release notes:

  * Comments in proto files are now collected and put into generated code as
    comments for corresponding classes and data members.
  * Added Parser to parse directly into messages without a Builder. For
    example,
      Foo foo = Foo.PARSER.ParseFrom(input);
    Using Parser is ~25% faster than using Builder to parse messages.
  * Added getters/setters to access the underlying ByteString of a string field
    directly.
