--------------------------------

    Fix Version/s: 1.0.1

> Most examples fail at startup because spark.master is not set
> -------------------------------------------------------------
>
>                 Key: SPARK-1974
>                 URL: https://issues.apache.org/jira/browse/SPARK-1974
>             Project: Spark
>          Issue Type: Bug
>          Components: Examples
>    Affects Versions: 1.0.0
>            Reporter: Sean Owen
>             Fix For: 1.0.1

>
> Most example code has a few lines like:
> {code}
> val sparkConf = new SparkConf().setAppName("Foo")
> val sc = new SparkContext(sparkConf)
> {code}
> The SparkContext constructor throws a SparkException if spark.master is not set though, so this fails immediately.
> What would be preferred -- let spark.master default to "local\[2\]"? or change all examples to call:
> {code}
> new SparkContext("local[2]", "Foo")
> {code}
