Voudrais savoir ce qu'il faut changer dans pom pour que les choses aillent de l'avant.

Dans le POM, vous avez la version Scala 2.11.7, mais plus tard dans les dépendances, vous déclarez que les dépôts Spark ont ​​été compilés avec 2.10:

<artifactId>spark-streaming_2.10</artifactId>
<artifactId>spark-core_2.10</artifactId>
<artifactId>spark-sql_2.10</artifactId>

Vous devez le changer pour:

<artifactId>spark-streaming_2.11</artifactId>
<artifactId>spark-core_2.11</artifactId>
<artifactId>spark-sql_2.11</artifactId>

Pour scala 2.12.0, vous devez ajouter la dépendance suivante à votre fichier POM.xml , et c'est tout.

<!-- https://mvnrepository.com/artifact/org.scala-lang/scala-library -->
<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>2.12.0-M1</version>
</dependency>
