Examples have SparkContext improperly labeled?

Hi all,

The examples listed here

https://spark.apache.org/examples.html

refer to the spark context as "spark" but when running Spark Shell
uses "sc" for the SparkContext.

Am I missing something?

Thanks!

RJ

Hi RJ,

Spark Shell instantiates a SparkContext for you named "sc".  In other apps,
the user instantiates it themself and can give the variable whatever name
they want, e.g. "spark".
