The second generation of SpatialHadoop that ships as an extension
Hello, I want to define my own object with SpatialHadoop to run a few experiments, I've got this [tutorial](http://spatialhadoop.cs.umn.edu/datatypes.html) from your website, a nice tutorial for beginners. But there are...
I am running the index command and it seems to be saving intermediate files into `hdfs://user/filename`. However spatialhadoop2 is looking for it in `hdfs://user/my.username/filename`. This is occuring at `edu.umn.cs.spatialHadoop.operations.FileMBR.fileMBRMapReduce(FileMBR.java:252)`. This...
I am reading the code of `src/edu/umn/cs/spatialHadoop/operations/Repartition.java`, which is to build index. Anyone can help to analyse the following function: ``` public static CellInfo[] packInRectangles(Path[] files, Path outFile, OperationsParams params,...
Suppose I have the the input file from `HDFS`, how to write code to build index using `Apache-spark`, just as `src/edu/umn/cs/spatialHadoop/operations/Repartition.java` do in spatial-hadoop?
Hi, I am trying to run the convex hull operation in spatialhadoop. Its giving nullpointerexception. Can you please help me? The full stack trace is bin/shadoop convexhull /user/hduser/points.grid /user/hduser/convexhull 14/07/28...
In `RandomSpatialGenerator#printUsage`, it says that when shape is set to polygon, it will generate random polygon. But in `RandomShapeGenerator#generateShape`, it only handles point and rectangle.
Creating an rtree index on point data fails. Have not looked into what's causing this yet. Here's the command to create the sample data hadoop jar /tmp/spatialhadoop-2-b2.jar generate testpoints mbr:0,0,10000000,10000000...
