这个问题在这里已经有答案了：

hadoop namenode格式化windows-java.lang.unsupportedoperationexception（2个答案）
8个月前关门了。
我键入了“hdfs namenode-format”命令来设置namenode。但我犯了下面这样的错误。

我从下载了hadoop-3.2.1和winutilshttps://github.com/cdarlint/winutils 只需覆盖bin目录，如下所示。这是hadoop-3.2.1/bin目录的列表
下面是core-site.xml配置。

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

hadoop-env.cmd（顺便说一下：我已经设置了java\u home的环境变量）：

@rem The java implementation to use.  Required.
set JAVA_HOME=%JAVA_HOME%

@rem The jsvc implementation to use. Jsvc is required to run secure datanodes.
@rem set JSVC_HOME=%JSVC_HOME%

hdfs-site.xml：

<configuration>

    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>/hadoop-3.2.1/data/namenode</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>/hadoop-3.2.1/data/datanode</value>
    </property>
</configuration>

yarn-site.xml：

<configuration>

<!-- Site specific YARN configuration properties -->
    <property>
        <name>yarn.nodemanager.resource.memory-mb</name>
        <value>1024</value>
    </property>
    <property>
        <name>yarn.nodemanager.resource.cpu-vcores</name>
        <value>1</value>
    </property>

</configuration>

我刚进入hadoop，对它完全陌生。有人能帮忙吗？提前谢谢。
