I am a newbie in the Hadoop world and I am trying to learn basics from this tutorial. I have freshly installed Hadoop 2.9.2 on my machine in a pseudo-distributed way and did the following setup.
core-site.xml
<configuration>
<propeerty>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</propeerty>
</configuration>
hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
mapred-site.xml
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
yarn-site.xml
<configuration>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
</configuration>
Ran bin/hdfs namenode -format which went well without any errors and then finally ran sbin/start-dfs.sh which gives me no errors with the following log

When I go to localhost:50070 I get nothing (site cannot be reached) and when I hit jps I don't see any namenode or secondary namenode running.
What have I done?
- Referred to Incorrect configuration: namenode address dfs.namenode.rpc-address is not configured and made sure that there are no spaces in any configs (already listed in the description)
Is there something that needs to be configured or anything that I am missing?
Thanks in Advance!
