Compiled from the latest version after git cloning the repo. When I try to run the following

$ bin/shadoop generate test mbr:0,0,1000000,1000000

What is the issue here?

You need to provide the type of shapes you're generating. You can use the following line for example:

$ bin/shadoop generate test mbr:0,0,1000000,1000000 shape:rect

I will modify the code to report a more meaningful error message.

Apologies for that. Many thanks.
