我正在尝试构建 spark-cassandra 连接器并点击此链接：

http://www.planetcassandra.org/blog/kindling-an-introduction-to-spark-with-cassandra/

链接中进一步要求从 git 下载连接器并使用 sbt 构建。但是，当我尝试运行命令时./sbt/sbt assembly。它抛出以下异常：

这对我有用，运行mvn -DskipTests clean package

  • 你可以从你的 spark 目录中找到文件build spark command。README.md
  • 在运行该命令之前，您需要通过设置 MAVEN_OPTS 来配置 Maven 以使用比平时更多的内存 export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"
