How to run a job (the simple way)
Danger zone: If you're running a backfill that hits an a/b test, I (Marcia) remember something about that not doing what you expect. Consider asking an expert (not Marcia), perhaps a Data Scientist or Analyser.

If your job is running into memory errors and you are using DatastoreInputReader, consider using DatastoreKeyInputReader instead.
Looking for the logs? Remember to select "mapreduce" in the "Module" dropdown, and you can filter by the job id. Or
Looking for the tasks?
