I have a project with spark 1.4.1 and scala 2.11, when I run it with sbt run ( sbt 0.13.12) it display an error is the following:

Knowing that I stopped the object of spark (sc.stop() ) at the end of my code, but I still got the same error. May be there is insufficient memory, I changed the configuration to a executor memory than the driver memory, in the following:
val conf = new SparkConf().setAppName("Simple project").setMaster("local[*]").set("spark.executor.memory", "2g")
val sc = new SparkContext(conf)
But always I have the same error. Can you help me by an ideas, where's exactly my error, in the configuration of the memory or another thing ?

Stopping the spark context (sc.stop()) without waiting for the job to complete could be the reason for this. Make sure you call sc.stop() only after calling all your spark actions.
