Subject [jira] [Commented] (SPARK-5260) Expose JsonRDD.allKeysWithValueTypes() in a utility class

Hi Corey,

The current permission setting disallow contributors from assigning themselves tickets. I
think the reason for it was because a lot of people didn't know well how this worked, and
assigned themselves tickets but were not actually working on them. I've assigned this to you.
Just ping us and we will assign it!

> I have found this method extremely useful when implementing my own strategy for inferring
a schema from parsed json. For now, I've actually copied the method right out of the JsonRDD
class into my own project but I think it would be immensely useful to keep the code in Spark
and expose it publicly somewhere else- like an object called JsonSchema.
