To implement Pseudo Node configuration for Hadoop on ubuntu

a) jdk

Single-Node Configuration

1. Create a dedicated user account for hadoop

2. Install java1.8 in folder /usr/local
   

3. Install Hadoop
   

4. Set the hadoop environment variables: Include the following lines in the $HOME/.bashrc file

5. Set hadoop environment variables: Include the following lines /etc/profile file

6. Run the.bashrc & profile files from the $ prompt for updating the changes
   $ bin/hadoop version

7. Configuration of the hadoop files: hadoop-env.sh, core-site.xml, mapred-site.xml, hdfs- site.xml and yarn-site.xml
   path :: /usr/local/hadoop-2.5.1/etc/hadoop

a) hadoop-env.sh
Include the following lines in hadoop-env.sh file

b) core-site.xml

Configure the directory for Hadoop to store its data files, the network ports it listens to, etc. Setup will use Hadoop’s Distributed File System (HDFS-single local machine)

Include the following lines in core-site.xml file between and tags

c) mapred-site.xml

 $sudo cp mapred-site.xml.template mapred-site.xml

Include the following lines in mapred-site.xml file

 <property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>

d) hdfs-site.xml Include the following lines in hdfs-site.xml file

e) yarn-site.xml Include the following lines in yarn-site.xml file

8. Format the Hadoop File system implemented on top of the local file system using
   

9. Start Hadoop using

$sbin/start-all.sh

Explore Hadoop using http://localhost:50070/ from the browser

10. The commonly used HDFS Commands are as follows:

11. Create a directory ‘/input’ in HDFS
    

12. Copy the input files into the distributed file system

13. Run some of the examples provided

14. Examine the output files
    
    Copy the output files from the distributed file system to the local file system and examine them:
    
    or View the output files on the distributed file system

Thus, the implementation of Pseudo Node configuration for Hadoop on ubuntu is successfully executed.# Ex-06-Pseudo-Node-Configuration-for-Hadoop-on-Ubuntu
