I got the same problem (caused NullPointerException when doing index). Do you find a solution?
In index command you need to mention "shape:rect". As it is not mention with SpatialHadoop sample commands but SpatialHadoop expects shape as mandatory parameter with each command
shape:rect param is missing.
