# R and Hadoop Integration | R Integration with Hadoop

## 1. R and Hadoop Integration

**R and Hadoop Integration**. Also, will learn when to use R and Hadoop combination. Moreover, will study the implementation of R integration with Hadoop. I recommend you to go through Hadoop and R Programming So lets start with integrating r and hadoop for big data analysis.

## 2. Introduction to R With Hadoop Integration

### a. Introduction to R Programming Language

### b. Introduction to Hadoop

## 3. R and Hadoop Integration Purpose

- Use Hadoop to execute R code

- Use R to access data stored in Hadoop

There are 4 types of methods for Integrating R with Hadoop

### a. R Hadoop

The R Hadoop is a collection of 3 packages. Here, we will discuss functionalities of packages.

#### i. The rmr package

#### ii. The rhbase package

**iii. The rhdfs package**

**HDFS**.

### b. Hadoop Streaming

**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**.

**R Language**. That makes it extremely user-friendly. As

**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 we need faster mapping and reducing steps with Hadoop. Hence, Hadoop streaming in demand and use. As we can write the codes in

**Python**, Perl or even Ruby.

### c. RHIPE

This is an integrated programming environment which was developed by the Divide and Recombine (D & R) for analyzing large amounts of data. As RHIPE stands for R and Hadoop Integrated Programming Environment.

### d. ORCH

It is called as Oracle R Connector. Also, it can be used to exclusively work with Big Data in Oracle appliance. Also, on a non-Oracle framework like **Hadoop**.

**Hadoop Distributed File System**.

## 5. Conclusion: R Integration with Hadoop

**Exploratory Data analysis with R**

can you provide more examples of R and Hadoop Integration.
