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.
- ST_Centroid now returns the geometry centroid rather than the center of its envelope (as of v2.1).
- Spatial Framework for Hadoop v2 is compatible with Geometry v2, Hive v2.3 & v3, and Jackson v2. Note: up-to-date releases may be available on Github but not on Maven Central.

Build as you would any other Mavenized repository. All dependencies are pulled automatically.
Ant build files are also available
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 (i.e., hive/build.xml).
The build files use Maven Ant Tasks for dependency
management. You will need the jar in a place Ant can find it (i.e., ~/.ant/lib/maven-ant-tasks-2.1.3.jar).
- Esri Geometry API for Java - Java geometry library for spatial data processing.
- Geometry 2.0
- Hive 0.11 and above (see Hive Compatibility issues) (For building from source, Hive-0.12+ is required.)
- Workflows calling MapReduce jobs require the location of the custom job to be run.
- 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.
