@gatorsmile small follow-up on the benchmarking. If I execute the following
code (note the ```.rdd.map(_.getLong(0))```):
val startTime = System.currentTimeMillis;
sqlContext.range(0, 10000000, 1, 15).rdd.map(_.getLong(0)).collect();
val endTime = System.currentTimeMillis;
val elapsed = (endTime - startTime)/ 1000.0
I get to an average of 845 ms per run (versus 477 for ```sc.range```).
