Dear Kavin Prabhu,

Hope you are doing well

1) Can you please send me the screen-shot of jps command in your ubuntu VM.

2) Here is the sample of core-site.xml file

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


3) Please download the following attachment and go through the installation guide.

Note : Download the hadoop 2.6.0 from the following command because previous link for hadoop 2.2.0 is not working due to server maintainence.
 

Now extract the tar file
 
tar -xvf hadoop-2.6.0.tar.gz


Please let me know if you have any further issue regarding this.
 
Feel free to contact us in case you have any query.
