Spark-HBase - GCP 模板 (2/3) - json4s 的版本问题？

如何解决Spark-HBase - GCP 模板 (2/3) - json4s 的版本问题？

我正在尝试在 GCP 上下文中测试 Spark-HBase 连接器并尝试遵循 1，它要求使用 Maven（我尝试过 Maven 3.6.3）为 Spark 本地打包连接器 [2] 2.4，并在Dataproc上提交作业时出现以下错误（完成[3]后）。

有什么想法吗？

感谢您的支持

解决方法

考虑阅读这些相关的 SO 问题：1 和 2。

在您遵循的教程以及指出的问题之一的幕后，使用 HortonWorks 提供的 Apache Spark - Apache HBase Connector。

问题似乎与 json4s 库的版本不兼容有关：在这两种情况下，似乎在构建过程中使用版本 3.2.10 或 3.2.11 将解决问题。

在 pom.xml (shc-core) 中添加以下依赖项：

<dependency>
  <groupId>org.json4s</groupId>
  <artifactId>json4s-jackson_2.11</artifactId>
  <version>3.2.11</version>
</dependency>
