Seems issue has already been fixed in spark 1.1.0 as per this Link

Spark : 1.1.0

就我而言，正如评论中所解释的那样，通过消除库冲突，我能够正确使用来自 kafka 的数据并将其存储到 cassandra，将作业部署到 Datastax 分析解决方案中。我发现与开源不同的是，streaming_kafka jar 和所有 scala 库都已包含在 executor 类路径中。

所以我建议如下：

  1. 确保您使用与 spark 相同版本的 scala 编译器。
  2. 确保 kafka 和 streaming_kafka jar 编译为相同版本。
  3. 检查 scala 库是否已包含在 executor 类路径中，而不是将它们包含在您的包中。

我假设您正在构建一个您尝试部署的 uber jar。

您缺少包含该方法的 Kafka jar。
