[英]Incompatibility between Dropwizard and hive-jdbc
I'm trying to create a WS REST using Dropwizard for getting a Hive result of a query and presenting in XML format. 我正在尝试使用Dropwizard创建WS REST,以获取查询的Hive结果并以XML格式呈现。 Each separated part of this could be done without error.
每个单独的部分都可以正确执行。
When I joined everything I reach a incompatibility between Dropwizard and hive-jdbc. 当我加入所有内容时,我在Dropwizard和hive-jdbc之间达到了不兼容的状态。 Apparently hive-jdbc has jersey 1 as dependency and Dropwizard has jersey 2.
显然,hive-jdbc具有球衣1作为依赖项,而Dropwizard具有球衣2。
I'm not sure if this is the problem. 我不确定这是否是问题。 I'd tried to exclude dependency in pom.xml, but didn't solve.
我试图排除pom.xml中的依赖关系,但没有解决。
I tried to make an application just putting hive-jdbc as dependency in pom.xml file without using or importing in any part of the code, and the error still happening. 我试图制作一个仅将hive-jdbc作为依赖项放入pom.xml文件的应用程序,而没有使用或导入代码的任何部分,并且该错误仍然发生。

I found that some users are getting similar error (as dropwizard and hive/hiverunner integration with maven and http://thread.gmane.org/gmane.comp.java.dropwizard.devel/461 ) 我发现有些用户遇到类似的错误(例如dropwizard和与Maven和http://thread.gmane.org/gmane.comp.java.dropwizard.devel/461的 hive / hiverunner集成 )
Is this (incompatibility in Jersey) the problem that is causing the error? 这是导致错误的问题(泽西岛不兼容)吗? Does anyone knows how to solve it?
有人知道如何解决吗?
Yup, its jersey conflict issue, exclude jersey 1 dependencies (com.sun.jersey) from both hive-jdbc and hadoop-core. Yup,它的球衣冲突问题,从hive-jdbc和hadoop-core中都排除了球衣1依赖项(com.sun.jersey)。 Had ran your test application and it worked with below exclusions.
已经运行了您的测试应用程序,并且可以使用以下排除项。
