windows - "yarn resourcemanager"产生 "The system cannot find the batch label specified - resourcemanager"

Question

我在 Windows 64 上以伪分布式模式运行 hadoop 2.7.1，无法运行 yarn。每当我尝试通过 yarn resourcemanager 启动它时，我都会得到以下输出:

The system cannot find the batch label specified - resourcemanager
Usage: java [-options] class [args...]
       (to execute a class)
or  java [-options] -jar jarfile [args...]
       (to execute a jar file)
where options include:

-d64          use a 64-bit data model if available
-server       to select the "server" VM
              The default VM is server.

我想这可能是我当前的 yarn-site.xml 的问题，但找不到它是什么:

<configuration>
<property>
    <name>yarn.resourcemanager.hostname</name>
    <value>localhost</value>
</property>
<property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
</property>
<property>

    </value>
</property>
</configuration>

正在关注 the only thing I managed to find on the internet about this issue我尝试在 Notepad++ 中编辑 yarn-site.xml，将 LF 更改为 CRLF，但这根本没有帮助。

尝试在位于 Notepad++ 中编辑 yarn.cmd，将 LF 更改为 CRLF
