我已经在windows上安装了单节点hadoop，它运行良好。
不幸的是，我不能在上面运行测试应用程序。
当我这么做的时候

hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.9.0.jar grep input output 'dfs[a-z.]+'

正如在它的页面上所描述的，我发现它没有返回到命令提示符。在我看到的工作页面上
yarnapplicationstate:已接受：等待分配、启动am容器并向rm注册。 Diagnostics: [Mon Apr 23 00:46:44 +0300 2018] Application is added to the scheduler and is not yet activated. Skipping AM assignment as cluster resource is empty.
