Reynold Xin closed SPARK-10861.

    Resolution: Won't Fix
      Assignee: Jihong MA

 I don't think this range function provides enough value (since it is just max 
- min for users) to justify adding it, because:

1. It is non-obvious what range means from the name.
2. There is already a range function on SQLContext. This one is just 
semantically confusing, but not incompatible since they are in different 
namespace.
3. There is already a range function in Python, which is incompatible with the 
range here.

I'm going to close the JIRA ticket as won't fix. Sorry about it.
