有人可以告诉我如何构建 Spark-Cassandra 连接器组件吗？我已经尝试按照 Github 页面https://github.com/datastax/spark-cassandra-connector上的说明进行操作，但我只收到数百个“重复数据删除”错误。

我将 Scala 2.11.7 与 Spark 1.5.1（我为 Scala 2.11 构建）和 SBT 13.8 一起使用。

我做了以下事情：

git clone https://github.com/datastax/spark-cassandra-connector.git
cd spark-cassandra-connector/
sbt -Dscala-2.11=true assembly

构建过程运行了一段时间，但随后开始吐出数百个“重复数据删除”错误并失败。我不知道从哪里开始解决这个问题，但据我所知，这个项目的程序集构建过程现在不起作用。

关于如何解决这个问题的任何提示？

看来 2.11 的构建已损坏，您应该将其报告给项目。现在不知道怎么修。
