MapReduce for Idiots

  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
  6. 6. Muhahahahahahahahahaha!
