How to install Apache Maven & Apache Hadoop in Ubuntu 16.04

In this article I  am going to discuss how to setup Maven and Hadoop. The steps for all two frameworks are always the same:

                    1.Decompress the archive

                    2.Add the correct console variable

                    3.Test the correctness of the installation

1. 1 Download Latest Maven binaries from apache site

First you have to go apache site using this link

http://it.apache.contactlab.it/maven/binaries/

You can download  latest version  of apache-maven-3.2.2 . You only have to click on the apache-maven-3.2.2-bin.tar.gz link. Then browser will automatically pop up window to download the file. 

1.2. Download Latest Hadoop from apache site

First you have to go apache site using this link

http://apache.panu.it/hadoop/common/hadoop-2.7.3

You can download  latest version  of hadoop-2.7.3. You only have to click on the hadoop-2.7.3.tar.gz link. Then browser will automatically pop up window to download the file. 

1.3 Then you can create folder named Hadoop (Folder name can be any one. I named folder as Hadoop :) ) in home directory . Then move downloded apache-maven-3.2.2-bin.tar.gz and hadoop-2.7.3.tar.gz  files from Downloads to newly created folder(Hadoop).

Next extract those files by right click on those files and select Extract Here. After that there are two files  named  apache-maven-3.2.2 and hadoop-2.7.3.

  

 2.1 We also need to have the  mvn command. The Hadoop command accessible from every terminal. To have this variable fixed even in case of a system reboot, we will save them in the bashrc file as well. 

There is an easy way in Ubuntu to set up variables for a single user.

2.2  To accomplish all these settings you need to:

 

Open the file named .bashrc using terminal. You have to type gedit ~/.bashrc  in terminal and enter. Then bashrc file will be opened.

2.3 Add the following lines at the end of the bashrc file according to your sytem:

 

 

export HADOOP_HOME=/home/kaveesh-pc/Hadoop/hadoop-2.7.3

export MAVEN_HOME=/home/kaveesh-pc/Hadoop/apache-maven-3.2.2

export PATH=$PATH:$MAVEN_HOME/bin:$HADOOP_HOME/bin

I placed hadoop-2.7.3 and apache-maven-3.2.2 in /home/kaveesh-pc/Hadoop directory. So my environment variables are like that. You just have to add your absolute path for each  hadoop-2.7.3 and  apache-maven-3.2.2 folder.

2.4 Save the file and return to the console.
The first two lines those are added to bashrc file ,create the user variables: MAVEN_HOME and HADOOP_HOME .

The last line couple those user variables(HADOOP_HOME and MAVEN_HOME)  with their relative bin locations to the PATH variable.

3  To test JDK and Maven, now type and enter the following command in terminal one by one:

 

         mvn –version

         hadoop version

You should received the following output:
