Hi Mike, We're actively developing the Files API, you may have noticed that we released a few new additions in the 1.7.1 release like listing files from Google Cloud Storage and improving the Files API MapReduce input reader. We're looking into the production issue you filed, please feel free to ping me directly if you have any other questions.
