R is an analytical tool and Hadoop is an open source framework that allows us to store and process large amount of data in distributed environment.

To integrate R with Hadoop, we need to install R in Linux environment because Hadoop works in Linux environment. Now we will describe some steps to install R and Rstudio in Centos. 

Step 1:  Before install R in Centos we need to install some libraries

            sudo yum install gfortran

sudo yum install build-essential

sudo yum install gcc-gfortran.x86_64

sudo yum install libX11-devel.x86_64

sudo yum install libXt-devel

sudo yum install readline-devel

Step 2:  Now Install R

          sudo yum install R

Step 3: Check whether R is install or not, to start R type following command in terminal

 sudo R

Through this command you will see R interface is open in Command prompt.

Step 4: After that we need to download Rstudio server, type following command in terminal

sudo wget https://download2.rstudio.org/rstudio-server-rhel-0.99.902-x86_64.rpm

Step 5: Enter into Download directory

             cd Download

             sudo cp /Downloads /home/cloudera

Step 6: Give Permissions and install Rstudio server

            sudo chmod777 /home/cloudera/rstudio-server-rhel-0.99.902-x86_64.rpm

sudo yum install --nogpgcheck rstudio-server-rhel-0.99.902-x86_64.rpm

Step 7: Start Rstudio server, open terminal and type,

            sudo Rstudio-server start

Step 8: Access Rstudio server on browser, go to browser type,

            <Your ip address>:8787
