Échec de l'exécution du nombre de mots par exemple Spark pour java

J'essayais d'exécuter l'exemple de nombre de mots spark à https://spark.apache.org/examples.html mais l'exécution échoue avec une erreur de pointeur null, je travaille dans un environnement autonome en utilisant les fichiers sur ma machine locale. ma console ressemble à ceci...

Je suis nouveau chez spark... ne peut pas comprendre où est-ce qu'il va mal... s'il vous plaît aider.

PS la première erreur java. io. IOException arrive également dans d'autres exemples mais n'entrave pas l'exécution aucunement.
