----------------------------------------------------------------------
Alright: switching to s3n:// fixed the issue.
I am not clear about why it did (the AWS documentation sometimes recommends s3,
sometimes s3n, and the AWS CLI sometimes supports s3n, sometimes it doesn't),
but I would be interested to know.
Also, if this workaround can be used in all situations, I guess that it would
be marked as a more minor bug?

> saveAsTextFile() on S3 first creates empty prefix
> -------------------------------------------------
>
> Key: SPARK-7141
> URL: https://issues.apache.org/jira/browse/SPARK-7141
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 1.3.1
> Environment: OS X 10.10
> Reporter: Eric O. LEBIGOT (EOL)
>
> Using {{saveAsTextFile("s3://bucket/prefix")}} actually adds an empty prefix,
> i.e. it writes to {{s3://bucket//prefix}} (note the double slash).
> Example code (in a {{pyspark}} shell):
> {{rdd = sc.parallelize("abcd")}}
> {{rdd.saveAsTextFile("s3://public_key:private_key@bucket/prefix")}}
> This is quite annoying, as the files cannot be saved in the intended location
> (they can be read, though, with the original path:
> {{sc.textFile("s3://bucket/prefix")}}, but the AWS console does not show them
> in the right place).
> Also, many {{block_*}} files are created directly in the bucket: shouldn't
> they be deleted? (This may be a separate issue, but maybe it is a path issue
> as well.)
