Reynold Xin resolved SPARK-15773.
---------------------------------
Resolution: Fixed
Assignee: Dongjoon Hyun
Fix Version/s: 2.0.0
> Avoid creating local variable `sc` in examples if possible
> ----------------------------------------------------------
>
> Key: SPARK-15773
> URL: https://issues.apache.org/jira/browse/SPARK-15773
> Project: Spark
> Issue Type: Task
> Components: Examples
> Reporter: Dongjoon Hyun
> Assignee: Dongjoon Hyun
> Priority: Minor
> Fix For: 2.0.0
>
>
> 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).
