As of March 2018, the archive runs Pig version 0.12.0, via CDH5.0.1 (Cloudera Distribution). "Local mode" unit tests in this folder run with Pig version 0.17.0 (controlled by `fetch_deps.sh`) due to [dependency/jar issues][pig-bug] in local mode of 0.12.0. [pig-bug]: https://issues.apache.org/jira/browse/PIG-3530 ## Development and Testing Fetch dependencies (pig): ./fetch_deps.sh Write .pig scripts here, and add a pytho wrapper test to `./tests/` when done. Test vector files (input/output) can go in `./tests/files/`. Install pipenv system-wide if you don't have it: # or use apt, homebrew, etc sudo pip3 install pipenv Run the tests with: pipenv run pytest Could also, in theory, use a docker image ([local-pig][]), but it's pretty easy to just download.
