I'm just copying-and-pasting to get something similar running externally.
Maybe it's a little surprising that the example code doesn't work that way --
being in a `main()` kind of suggests this is a stand-alone program. Maybe just
me.
I think there are a few possibilities:
- Change all example code to set master if missing (that's what the current
PR does)
- Change SparkConf to do something similar as a global default
- Just update javadoc to make it clear that the examples require the
`spark.master` system property to be set
I slightly prefer one of the first two on the principle of least surprise,
but can go any direction. I think at least the third should be done. What say
everyone?
