Java IntelliJ不显示hadoop错误

我在

IntelliJ

中将所有环境设置为运行

hadoop

应用程序。现在，我遇到了一些问题，因为我的代码在编译时没有错误消息，尽管我没有

hadoop

输出

因此，我必须构建工件，在本地的hadoop上运行它，然后得到这个错误

Found interface org.apache.hadoop.mapreduce.TaskAttemptContext, but class was expected
    at org.apache.hadoop.mapred.LocalJobRunner$Job.runTasks(LocalJobRunner.java:462) 

然后我就可以调试它了。我的问题是为什么我的

IntelliJ

控制台中没有显示此错误

编辑：在屏幕截图中，

运行配置

设置

还有我的地方司令部

IntelliJ的行为与hadoop命令不同的原因是主类不同

IntelliJ的“运行配置”将ParseXML显示为JVM的主类，而

hadoop

命令将作为主类运行，主类将使用ParseXML类及其参数作为程序参数

---

除了主类之外，您还可以检查（它只是一个shell脚本；

sh-x

help）在调用

java

命令的主类之前，查看它对环境变量和系统属性的作用。

有趣的观察。你能提供IntelliJ的“运行配置”和本地hadoop命令参数吗？@gonbe我刚刚做了一个编辑。这就是你要找的信息吗？很好。您添加了IntelliJ设置及其run命令。您能提供您的“local hadoop”命令吗？该命令也会给出异常消息？@gonbe:my hadoop命令只是

hadoop jar myartifact.jar input.avro output

我发现程序参数有差异。您是否可以尝试使用与hadoop命令相同的参数更新IntelliJ运行配置？有趣的观察结果。你能提供IntelliJ的“运行配置”和本地hadoop命令参数吗？@gonbe我刚刚做了一个编辑。这就是你要找的信息吗？很好。您添加了IntelliJ设置及其run命令。您能提供您的“local hadoop”命令吗？该命令也会给出异常消息？@gonbe:my hadoop命令只是

错误如果我理解正确，您希望比较旧类和ParseXML类（两者都在IntelliJ中运行）。你愿意分享吗？谢谢你的回答，但实际上我曾经有一些代码，我用同样的方式命名，它正确地显示了
