The Spatial Framework for Hadoop allows developers and data scientists to use the Hadoop data processing system for spatial data analysis. For tools, samples, and tutorials that use this framework, head over to GIS Tools for Hadoop. At the root level of this repository, you can build a single jar with everything in the framework using Apache Ant. Alternatively, you can build a jar at the root level of each framework component. Custom MapReduce jobs that use the Esri Geometry API require that the developer has authored the job, (referencing the com.esri.geometry.* classes), and deployed the job Jar file to the Hadoop system, prior to the ArcGIS user submitting the workflow file.
