List of exceptions and troubleshooting steps that I have encountered till now using Spark in my project.
Issue 1 # Exception in thread “main” org.apache.spark.SparkException: A master URL must be set in your configuration
Fix : It means you simply forgot to specify the master URL.
SparkConf configuration = new SparkConf() .setAppName(“Your Application Name”) .setMaster(“local”);
Issue 2 # <Next_Exception_will_be_listed_soon>
