IntelliJ没有显示Hadoop错误

Question

我将所有环境设置为在IntelliJ运行hadoop应用程序。 现在，我遇到了一些问题，因为尽管我没有hadoop输出，但是我的代码仍在编译，没有错误消息。

因此，我必须构建工件，在本地hadoop上运行它，然后得到此错误

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

然后，我可以对其进行调试。 我的问题是，为什么此错误未在IntelliJ控制台中显示？

编辑：在屏幕快照中， run configuration设置。

和我的本地命令

Answer 1

您的IntelliJ行为与hadoop命令不同的原因是因为主类不同。

您的IntelliJ的“运行配置”将ParseXML作为JVM的主类，而hadoop命令将RunJar作为主类运行，它将把您的ParseXML类及其参数作为程序参数。

除了主类之外，您还可以在调用java命令的主类之前检查hadoop命令 （这只是一个shell脚本； sh -x可以帮助您）了解它对环境变量和系统属性的作用。
