apache-spark - Hive Warehouse Connector + Spark = 签名者信息与同包中其他类的签名者信息不匹配

问题描述

即使使用最简单的示例（如下） ，我也正在尝试使用hive warehouse connector并获得异常。导致问题的类：- 位于（spark_sql 的依赖项）和.sparkhdp 3.1JaninoRuntimeExceptionorg.codehaus.janino:janino:jar:3.0.8com.hortonworks.hive:hive-warehouse-connector_2.11:jar

我试图从 spark_sql 中排除 janino 库，但这导致 janino 中缺少其他类。我需要 hwc 来获得新功能。

有人有同样的错误吗？任何想法如何处理它？

我收到错误：

解决方案

经过一番调查，我发现错误的存在取决于classpath.

由于未知原因，当我在 IntelliJ IDEA 中运行这个项目时，类路径总是随机顺序，应用程序失败并随机成功。

最后 - HiveWarehouseConnectorjar inclasspath应该在 Spark Sqljar 之后。

更新

正如这个答案中所建议的 - IntelliJ IDEA 中的顺序可以在依赖项选项卡中更改。

否则 - 我无法为 IntelliJ 解决这个问题 - 顺序总是随机的，但是当我在 IntelliJ 之外执行程序时 - 我设置了我需要的顺序。
