Reading from /tmp no longer working

su — Fri, 14 Oct 2022 13:29:43 GMT

Since yesterday, reading a file copied into the cluster is no longer working.

What used to work:

blob = gcs_bucket.get_blob("dev/data.ndjson") -> works

blob.download_to_filename("/tmp/data-copy.ndjson") -> works

df = spark.read.json("/tmp/data-copy.ndjson") -> fails

When calling os.listdir('/tmp'), the file is listed as expected.

This worked yesterday. Has something changed?

I encountered this same issue, and figured out a fix!

For some reason, it seems like only %sh cells can access the /tmp directory. So I just did...

%sh ch /tmp/<file> /dbfs/<desired-location> and then accessed it form there using Spark.
