I typed "hdfs namenode -format" command to set the namenode. But I got an error like below.

I downloaded hadoop-3.2.1 and winutils from https://github.com/cdarlint/winutils to simply override the bin directory like below. This is the list of hadoop-3.2.1/bin directory
Below is the core-site.xml configuration.
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
The hadoop-env.cmd (BTW: I already set the enviroment variable of JAVA_HOME):
@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%
The 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>
The 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>
I just got into hadoop and totally new about it. Could anyone help on it? Thanks in advance.
