  1. 1. MapReduce for idiots (like me)
  2. 2. You don’t need it (probably)
  3. 3. Optimizes out seeks
  4. 4. Streaming is simple mapper is print “12345 data”; reducer combines adjacent lines with the same key in bash: ./mapper.php < input.txt | sort | ./reducer.php > output.txt
  5. 5. Elastic MapReduce Hadoop without the blood-sacrifices
