This integration allows you to process large data volumes on Amazon EMR which otherwise would not be possible using R in stand- alone mode. The RHadoop packages combine R with Hadoop and allow you to marry R’s statistical capabilities with the scalable compute power provided by Amazon EMR on top of the Hadoop MapReduce framework. In recent years several packages were published to solve high-memory requirements and long computation times. Traditionally, R was not designed to handle large amount of data. Furthermore, the RHadoop project provides packages to connect with Apache HBase and to execute functionality from the famous plyr package on Hadoop. It uses Hadoop Streaming to send jobs from R to Hadoop and works for the Hadoop distributions CDH3 and higher, or Apache 1.0.2 and higher. The open source project RHadoopprovides several R packages to work with R and Hadoop interactively. This allows data scientists, statisticians and other sophisticated enterprise users to leverage R within their analytics package.
Nearly every top vendor of advanced analytics has integrated R and can now import R models. It is the fastest-growing analytics platform in the world, and is established in both academia and business due to its robustness, reliability, and accuracy.
Due to its flexible package system and powerful statistical engine, the statistical software R can provide methods and technologies to manage and process a big amount of data. R is an open source programming language and software environment designed for statistical computing, visualization and data. At the end of this post, I’ve added a Big Data analysis using a public data set with daily global weather measurements. This combination provides a powerful statistical analyses environment, including a user-friendly IDE on a fully managed Hadoop environment that starts up in minutes, and saves time and money for your data-driven analyses.
This blog post describes how to set up R, RHadoop packages and RStudio server on Amazon Elastic MapReduce (Amazon EMR).
Another technology shaking things up in Big Data is R. It is synonymous with technologies like Hadoop and the ‘NoSQL’ class of databases. Markus Schmidberger is a Senior Big Data Consultant for AWS Professional Servicesīig Data is on every CIO’s mind.
