Since RHadoop is considered as matured, we will consider it while performing data analytics in further chapters. In Chapter 5, Learning Data Analytics with R and Hadoop and Chapter 6, Understanding Big Data Analysis with Machine Learning, we will dive into some Big Data analytics techniques as well as see how real world problems can be solved with RHadoop. So far we have learned how to write the MapReduce program with R and Hadoop using RHIPE and RHadoop. In the next chapter, we will see how to write the Hadoop MapReduce program with Hadoop streaming utility and also with Hadoop streaming R packages.
