Apache Hop RScript

Apache Hop R Integration Plugin is used to execute R code direct from Apache Hop (Hop). This plugin is overwritten from the pentaho original created by dekarlab.

Building

The Hop RScript Plugin is built with Maven.

   $ git clone https://github.com/ravamo/hop-rscript.git
   $ cd hop-rscript
   $ mvn clean install

This will produce a plugin archive in target/hop-rscript-${version}.zip. This archive can then be extracted into your Hop plugin/transforms directory.

Instalation in Apache hop

R script plugin can be installed by performing the following steps:

1. Copy the plugin folder (RScriptPlugin) into the folder of your Hop installation: apache-hop-client-{version}\hop\plugins\transforms
2. Install R project from the site http://www.r-project.org/
3. Install rJava package in R by executing: install.packages("rJava")
4. Copy JRI library rJava/jri/jri.dll (windows) or rJava/jri/libjri.so (linux) to: hop/libswt/{youroperation system}, for example: hop/libswt/win64
5. Specify location of R using R_HOME environment variable. (like: C:\R\R-3.0.2).
6. For windows, it is also needed to put in PATH variable the path to R.dll, for example: C:\R\R-{your vresion}\bin{your operation system}
