Dropwizard和hive-jdbc之间不兼容

Question

我正在尝试使用Dropwizard创建一个WS REST，以获取查询的Hive结果并以XML格式呈现。其中每个单独的部分都可以无误地完成。

当我加入所有内容时，我遇到了Dropwizard和hive-jdbc之间的不兼容。显然，hive-jdbc 将球衣 1 作为依赖项，而 Dropwizard 有球衣 2。

我不确定这是否是问题所在。我试图排除pom.xml中的依赖关系，但没有解决。

我试图制作一个应用程序，只是将 hive-jdbc 作为依赖项放在 pom.xml 文件中，而不使用或导入代码的任何部分，并且错误仍在发生。

我发现一些用户遇到了类似的错误(作为dropwizard和hive/hiverunner与maven和 http://thread.gmane.org/gmane.comp.java.dropwizard.devel/461 的集成(

这是(泽西岛不兼容(是导致错误的问题吗？有谁知道如何解决它？

是的，它的球衣冲突问题，从Hive-JDBC和Hadoop-core中排除了jersey 1依赖项(com.sun.jersey(。运行了您的测试应用程序，它适用于以下排除项。
