问题描述
我已经在 windows hadoop-2.7.0 上安装/配置了 Hadoop
I have installed/configured Hadoop on windows hadoop-2.7.0
我可以成功启动sbinstart-dfs"运行命令.DataNode 和 NameNode 启动.我可以创建目录，将文件添加到hadoop系统中.
I could successfully start "sbinstart-dfs" run command. DataNode and NameNode started.I could create directory, add file into hadoop system.
但是现在当我在resourcemanager"窗口上尝试sbin/start-yarn"时，我没有看到错误.但它在纱线的namenode"上失败
But now when I try "sbin/start-yarn" on "resourcemanager" window I do not see error. But it failes on yarn's "namenode"
它因这个错误而失败:-
it fails with this error :-

我在sbinstart-dfs"时遇到过类似的问题.我尝试了不同的东西.当我在路径中添加hadoop的bin"和sbin"时，它看起来已经解决了.
I had faced similar problem while "sbinstart-dfs". I tried different things. It looks like it was solved when I added hadoop's "bin" and "sbin" in path.
你能建议 Yarn 问题的解决方案吗?
Can you please suggest the solution for Yarn problem.
推荐答案
应该有一个 %HADOOP_HOME%inhadoop.dll 包含 方法.%HADOOP_HOME%in 应该在路径中.如果您从源代码构建，请确保构建并放置了 hadoop.dll.
there should be a %HADOOP_HOME%inhadoop.dll which contains the native method. %HADOOP_HOME%in should be in the path. If you built from source, make sure the hadoop.dll was built and placed.
