Weston Pace commented on ARROW-15419:
-------------------------------------
A few things to check:
* Arrow's S3 implementation will check the usual places (e.g.
~/.aws/credentials on Linux) to try and automatically detect credentials to use.
* S3's API will attempt to authenticate with those credentials even if it is
accessing a public resource.
So you might try removing (or temporarily moving) any credentials files first
and then try accessing it again.
I've even ran into issues where accessing public data only works if you are
accessing it anonymously (but I didn't think that was the case for the Ursa
taxi data).
You might also check any config files to see if there is a default region set.
The Ursa labs taxi data is in us-east-2.
