title: Which distribution of hadoop is better?
body: <p>I am working with massive data, my input data is about 100 GB.I want to choose one of the hadoop distributions, but i don't know to choose mapr cluster or cloudera cluster. i want to use free versions(mapr M3 and cloudera CDH4 that uses hadoop 0.20).
  which of them is better? which configurations do i use that they work the best?
  Thanks.</p>
