Pydoop includes several usage examples: you can find them in the “examples” subdirectory of the distribution root.

Python Dependencies

If you’ve installed Pydoop or other Python packages needed by your application in a non-standard location (e.g., /opt/lib/python3.6/site-packages), the Python code that runs within Hadoop tasks might not be able to find them. Note that, according to your Hadoop version or configuration, map and reduce tasks might run as a different user than the one who launched the job. If you can’t install globally, Pydoop offers the option of shipping packages automatically upon job submission, see the section on installation-free usage.

Input Data

Most examples, by default, take their input from a free version of Lewis Carrol’s “Alice’s Adventures in Wonderland” available at Project Gutenberg (see the examples/input sub-directory).
