Get JavaSparkContext from a SparkSession

Question

Im am using a SparkSession to run my spark application because I use a lot of spark-sql features. I would like to use the JavaSparkContextto create an RDD from a list. But via the Session I can only get an ordinary SparkContext. Is there a way to transform the context in this direction?

Answer 1

After determining the SparkContext, you could use:

SparkContext sc = ...
JavaSparkContext jsc = JavaSparkContext.fromSparkContext(sc);

This will return you the new instance of JavaSparkContext, but there is no problem as long as you maintain just one active instance of the SparkContext.
