>                 Key: SPARK-15773
>                 URL: https://issues.apache.org/jira/browse/SPARK-15773
>             Project: Spark
>          Issue Type: Task
>          Components: Examples
>            Reporter: Dongjoon Hyun
>            Priority: Minor
>
> Instead of using local variable `sc` like the following example, this issue uses `spark.sparkContext`. This makes examples more concise, and also fixes some misleading, i.e., creating SparkContext from SparkSession.
> {code}
> -    println("Creating SparkContext")
> -    val sc = spark.sparkContext
> -
>      println("Writing local file to DFS")
>      val dfsFilename = dfsDirPath + "/dfs_read_write_test"
> -    val fileRDD = sc.parallelize(fileContents)
> +    val fileRDD = spark.sparkContext.parallelize(fileContents)
> {code}
> This will change 12 files (+30 lines, -52 lines).
