Hi, someone can help
I'm trying to use parquet in IBM Block Storage at Spark but when I try to load
get this error:
using this config

In my own code, I'd assume that the value of credentials['name'] didn't match
that of the URL, assuming you have something like swift://bucket.keystone .
Failing that: the options were set too late.
Instead of asking for the hadoop config and editing that, set the option in
your spark context, before it is launched, with the prefix "hadoop"
