I was trying to install Hadoop
and run a simple sample program
Datanode started only for "1" - one time and then I started getting this error
```

I have referred to many different articles but to no avail. I have tried to use another version of Hadoop but the problem remains and as I am just starting out, I can't fully understand the problem therefore I need help
these are my configurations
```
-For core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
- For mapred-site.xml
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
-For yarn-site.xml
<configuration>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.nodemanager.auxservices.mapreduce.shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
</configuration>
-For hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>C:\hadoop\data\namenode</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>datanode</value>

</configuration>
```
