10. def getOrCreate(): SparkContext

    

    This function may be used to get or instantiate a SparkContext and register it as a singleton object.

    This function may be used to get or instantiate a SparkContext and register it as a singleton object. Because we can only have one active SparkContext per JVM, this is useful when applications may wish to share a SparkContext.

    This method allows not passing a SparkConf (useful if just retrieving).

    Note: This function cannot be used to create multiple SparkContext instances even if multiple contexts are allowed.

11. def getOrCreate(config: SparkConf): SparkContext
