A key paragraph in Arun Murthy’s post about Apache Hadoop YARN:
MapReduce is great for many applications, but not everything; other programming models better serve requirements such graph processing (Google Pregel / Apache Giraph) and iterative modeling (MPI). When all the data in the enterprise is already available in Hadoop HDFS, multiple paths for processing data is critical.
That’s for all the critiques Hadoop is getting.
