Presumedly like most I've started off with mainly using "Text" based input and output formatters and using key and values as Text or IntWritable. I've been looking more into the other formatters and writable classes and wondering what they would do for me. To help spur some best practices and lessons learned conversations: What are the benefits of the other formatters? And benefits of MapFiles and SequenceFiles? What are people out there using or have found gave them the greatest benefits?
