Hadoop mapreduce 容器以非零退出代码 1 退出

Question

我正在尝试运行一些 hadoop 程序来提取 Ubuntu 中一些摘要的关键字。当我使用 Hadoop 运行程序时，出现以下错误。

 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

这个错误的原因是什么？

请注意，为了在我的代码中使用 lucene 库，我将我的 mapreduce 项目转换为 maven 项目。

你的资源管理器真的在/0.0.0.0:8032 上吗？它还表明您没有使用 Toolrunner，因此请尝试重写您的 mapreduce Hadoop: Implementing the Tool interface for MapReduce driver .

希望对你有帮助
