R and Hadoop Integration – Enhance your skills with different methods!
We will study about the R integration with Hadoop in this tutorial. We will provide you with different methods of R and Hadoop integration for Big Data analysis.
Without wasting any time, let’s start the tutorial.
What is R Programming?
R is an open-source programming language. It is best suitable for statistical and graphical analysis. Also, if we are in need of strong data analytics and visualization features, then we need to combine R with Hadoop.
What is Hadoop?
Hadoop is an open-source tool which is founded by the ASF – Apache Software Foundation. It’s also an open-source project which means it is freely available and one can change its source code as per the requirements. Although, if the certain functionality does not fulfil your need, you can also alter it as per your needs. Moreover, it provides an efficient framework for running jobs.

The purpose behind R and Hadoop Integration
- Use Hadoop to execute the R codes.
- Use R to access the data stored in Hadoop.
R and Hadoop Integration Methods
There are four types of methods for integrating R programming with Hadoop:
1. R Hadoop
The R Hadoop method is a collection of 3 packages. Here, we will discuss the functionalities of the three packages.
- The rmr package
- The rhbase package
- The rhdfs package
It’s the file management capabilities by integration with HDFS.

2. Hadoop Streaming
It’s R database management capability with integration with HBase. Hadoop streaming is the R Script available as part of the R package on CRAN. Also, this intends to make R more accessible to Hadoop streaming applications. Moreover, using this you can write MapReduce programs in a language other than Java.
It involves writing MapReduce codes in R language, which makes it extremely user-friendly. Java is the native language for MapReduce but according to today’s need, it doesn’t suit high-speed data analysis. Thus, in toady’s time, we need faster mapping and reducing steps with Hadoop. Hadoop streaming has gained huge demand as we can write the codes in Python, Perl or even Ruby.
Time to learn the installation process of R Packages
RHIPE stands for R and Hadoop Integrated Programming Environment. Divide and Recombine developed this integrated programming environment for carrying out efficient analysis of a large amount of data.
It involves working with R and Hadoop integrated programming environment. Also, one can use Python, Java or Perl to read data sets in RHIPE. There are various functions in RHIPE that lets you interact with HDFS. Hence, this way you can read, save the complete data that is created using RHIPE MapReduce.
It is called as Oracle R Connector. It can be used to particularly work with Big Data in Oracle appliance and also, on a non-Oracle framework like Hadoop.
It helps in accessing the Hadoop cluster via R and also to write the mapping and reducing functions. Also, one can manipulate the data residing in the Hadoop Distributed File System.
