This is a standalone project of the cascalog tutorial. It is no different from the tutorial in cascalog proper. The project exists for easier inclusion in the Cascading SDK. It is not meant for direct download from gitub, it is used by the buildsystem of concurrent inc, when assembling the SDK.
If you however want to use it for your own purpose anyway do the following:
gradle runLeiningen
This will create the directory build/assembly/cascalog-tutorial-standalone,
which is a fully working leiningen 2 project. The project will contain a lib
directory with all jars necessary for running cascalog. There is also a task for
creating a tarball and for uploading the tarball into S3, which are used for
creating the SDK.
