When I run hdfs namenode -format to format namenode, I am getting this following error:

11/01/19 15:18:58 WARN namenode.FSEditLog: No class configured for C, dfs.namenode.edits.journal-plugin.C is empty

Change your following properties in hdfs-site.xml

<property>
   <name>dfs.namenode.name.dir</name>
   <value>C:/hadoop/data/namenode</value>
</property>
<property>
   <name>dfs.datanode.data.dir</name>
   <value>C:/hadoop/data/datanode</value>
</property>

to

<property>
   <name>dfs.namenode.name.dir</name>
   <value>/hadoop/data/namenode</value>
</property>
<property>
   <name>dfs.datanode.data.dir</name>
   <value>/hadoop/data/datanode</value>
</property>

Can you share the contents of hdfs-site.xml file?

Hi Wenzel,

Try to check your configuration, because it should start on 9000 port.

<configuration> 

 <property> 

 <name>fs.defaultFS</name>

 <value>hdfs://localhost:9000</value>

 </property> 

</configuration>
