Research direction
Start by reproducing the default c4 download for the en.realnewslike configuration with tensorflow-datasets 3.1.0 and Python 3.7, focusing on the Dataflow Map(download_url) step and the Common Crawl S3 URL shown. Determine whether the timeout is reproducible and what failure behavior the downloader is expected to provide; the issue is resolved when the cause and an actionable fix or limitation are established.
