I was reviewing a video from Hadoop Summit 2011[1] where Arun Murthy mentioned that MRv2 was moving towards protocol buffers as the wire format but I feel like this is contrary to an Avro presentation that Doug Cutting did back in Hadoop World '09[2]. I haven't stayed up to date with the Jira for MRv2 but is there a disagreement between contributors as to which format will be the de facto standard going forward and if so what are the biggest points of contention? The only reason I bring this up is I am trying to integrate a serialization framework into our best practices and, while I am currently working towards Avro, this disconnect caused a little concern.
