无法在DSE 6.7中创建SparkSession

我已将DSE 5.1升级到DSE 6.7。 我们正在使用启用火花的分析节点进行火花作业。

我正在使用以下方法创建sparkSession对象：

SparkSession
  .builder()
  .appName("App Name")
  .config("spark.cassandra.connection.host", "host")
  .config("spark.cassandra.connection.port", "port")
  .config("spark.cassandra.auth.username", "username")
  .config("spark.cassandra.auth.password", "password"))
  .enableHiveSupport()
  .getOrCreate();

在DSE 5.1中工作正常，但在DSE 6.7中引发以下错误

DSE Analytics基于Spark 2.2，而不是Spark 2.3.0作为您正在使用的连接器。对于DSE，我建议对特定版本使用DSE依赖项，例如：

$\

Spark构建示例已更新至6.7.0，因此您可以从那里获取依赖项：https://github.com/datastax/SparkBuildExamples/blob/master/scala/maven/dse/pom.xml
