Version 2.1
- Preliminary support for HDF files in MODIS datasets brought by NASA.
- SpatialHadoop operations are now easier to access through a new bin/shadoop command
- Several bug fixes in visualization operations
Version 2 beta 2
- An all new PlotPyramid operation that plots a set of tiles ready to be visualized using an engine similar to Google Maps. Users can control the size of each tile as well as the number of zoom levels generated.
Version 2 beta 0
- Version 2 of SpatialHadoop is a remodel of the system that is much more flexible and powerful. Most importantly, this version ships mainly as an extension which can be plugged into an existing Hadoop cluster. This means you can keep using your own Hadoop cluster and just extend it with spatial capabilities by installing SpatialHadoop on it. You still get the orders of magnitude performance improvement because SpatialHadoop classes work with the core Hadoop allowing it to efficiently process spatial data.
-
SpatialHadoop v2 also ships with many new features and improvements.
- Basic data types now support double precision numbers for coordinates

SpatialHadoop is designed in a generic way which allows it to run on any configured Hadoop cluster. SpatialHadoop was tested on Apache Hadoop 1.2.1 but it should run seamlessly on other distributions of Hadoop as well. First, you need to setup traditional Hadoop. Once Hadoop is configured, you can install SpatialHadoop on that distribution which adds the new classes and configuration files to the cluster allowing the new commands to be used. This tutorial will take you through the process of setting up SpatialHadoop on a single machine and running some examples. It can be easily expanded to a cluser of machines by following this tutorial.
Prerequisites
- This tutorial sets up SpatialHadoop on Linux. If you want to run SpatialHadoop on Windows, you can try Hortonworks.
- JavaTM 1.6.x, preferably from Sun, must be installed. We recommend using Java 1.6.0_24. ?

Configure on one machine
- Download and extract your preferred version of Hadoop. We tested the latest version of SpatialHadoop on Apache Hadoop 2.7.2.
- Extract the downloaded compressed file into the home directory of Hadoop.
- Edit etc/hadoop/hadoop-env.sh in your Hadoop home directory and set JAVA_HOME to your current Java installation. ?

Once you have SpatialHadoop configured correctly, you are ready to run some sample programs. The following steps will generate a random file, index it using a Grid index, and run some spatial queries on the indexed file. The classes needed for this example are all contained in the spatialhadoop*.jar shipped with the binary release. You can type 'bin/shadoop' to get the usage syntax for the available operations.
To generate a random file containing random rectangles, enter the following command
$ bin/shadoop generate test mbr:0,0,1000000,1000000 size:1.gb shape:rect
This generates a 1GB file named 'test', where all rectangles in the file are contained in the rectangle with corner at (0,0) and dimensions 1Mx1M units.
If you have your own file that needs to be processed, you can upload it the same way you do with traditional Hadoop by typing
$ bin/hadoop fs -copyFromLocal <local file path> <HDFS file path>
Then you can index this file using the following command
To index this file using a Grid index
$ bin/shadoop index test test.grid mbr:0,0,1000000,1000000 sindex:grid shape:rect
To see how the grid index partitions this file, type:
$ bin/shadoop readfile test.grid
This shows the list of partitions in file, each defined by boundaries, along with the number of blocks in each partition.
To run a 手机ip地址更换国外 operation on this file
$ bin/shadoop rangequery test.grid rq_results rect:500,500,1000,1000 shape:rect
This runs a range query over this file with the query range set to the rectangle at (500,500) with dimensions 1000x1000. The results will be stored in an HDFS file named 'rq_result'
To run a knn query operation on this file

This runs a knn query where the query point is at (1000,1000) and k=1000. The results are stored in HDFS file 'knn_results'
To run a spatial join operation
First, generate another file and have it indexed on the fly using the command
$ bin/shadoop generate test2.grid mbr:0,0,1000000,1000000 size:100.mb sindex:grid shape:rect
Now, join the two files via the Distributed Join algorithm using the command
$ bin/shadoop dj test.grid test2.grid shape:rect sj_results
