+Code in tihs repository is potentially public!

-## Python Setup
+**./python/** contains Hadoop streaming jobs written in python using the
+`mrjob` library. Most notably, the **extraction** scripts, which fetch PDF
+files from wayback/petabox, process them with GROBID, and store the result in
+HBase.
-Pretty much everything here uses python/pipenv. To setup your environment for
-this, and python in general:
+**./scalding/** contains Hadoop jobs written in Scala using the Scalding
+framework. The intent is to write new non-trivial Hadoop jobs in Scala, which
+brings type safety and compiled performance.
- # libjpeg-dev is for some wayback/pillow stuff
- sudo apt install -y python3-dev python3-pip python3-wheel libjpeg-dev build-essential
- pip3 install --user pipenv
+**./pig/** contains a handful of Pig scripts, as well as some unittests
+implemented in python.
-On macOS:
+## Running Hadoop Jobs
- brew install libjpeg pipenv
+The `./please` python3 wrapper script is a helper for running jobs (python or
+scalding) on the IA Hadoop cluster. You'll need to run the setup/dependency
+tasks first; see README files in subdirectories.
-Each directory has it's own environment. Do something like:
-
- cd python
- pipenv install --dev
- pipenv shell
-
-## Possible Issues with Setup

-Bryan had `~/.local/bin` in his `$PATH`, and that seemed to make everything
-work.
