Hi,
When I run the following code within a bigger function there is an error
SparkConf sparkConf = new
SparkConf().setAppName("ContactListenerExample").setMaster("local[2]").set("spark.executor.memory","1g");
SparkContext sc = new SparkContext(sparkConf);
Here is the error:
java.lang.NumberFormatException: For input string: "unknown"

Does anyone know what is causing it?
Thank you,
