Dongjoon Hyun created SPARK-15773:
-------------------------------------
Summary: Avoid creating local variable `sc` in examples
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).
