Need config params while doing rdd.foreach or map

[Kamalanathan Venkatesan]

Hello All,

I have custom parameter say for example file name added to the conf of spark 
context example  SparkConf.set(INPUT_FILE_NAME, fileName).
I need this value inside foreach performed on an  RDD, but the when access 
spark context inside foreach, I receive spark context is null exception!

Code sample:

val conf = new 
SparkConf().setMaster(appConfig.envOrElseConfig("app.sparkconf.master"))
      .setAppName(appConfig.envOrElseConfig("app.appName"))
      .set("INPUT_FILE_NAME", fileName)

var sparkContext = new SparkContext(conf)

sparkContext.addJar(sparkContextParams.jarPath)

var sqlContext = new SQLContext(sparkContext)

var df = sqlContext.read.format("com.databricks.spark.csv")
     .option("header", "true")
      .load(<filePath>)

df.foreach( f=> {
       f.split(",")
       println(sparkContext.getConf.get("INPUT_FILE_NAME"))
});

The above sparkContext.getConf.get("INPUT_FILE_NAME") throws null pointer 
exception!

Thanks,
Kamal.
