If you want your Hive queries to be launched from the R interface, then RHIVE is the go-to package with functions for retrieving metadata such as database names, column names, and table names from Apache Hive. RHIVE provides rich statistical libraries and algorithms available in the R programming language for the data stored in Hadoop by extending HiveQL with R language functions. RHIVE functions allow users to apply R statistical learning models to the data stored in Hadoop cluster that has been cataloged using Apache Hive. The advantage of using RHIVE for Hadoop R integration is that it parallelizes operations and avoids data movement because data operations are pushed down into Hadoop.
