Neal Richardson updated ARROW-17201:
------------------------------------
Summary: [R] Cannot override environmental variables setting AWS S3 region
(was: Cannot override environmental variables setting region)
> [R] Cannot override environmental variables setting AWS S3 region
> -----------------------------------------------------------------
>
> Key: ARROW-17201
> URL: https://issues.apache.org/jira/browse/ARROW-17201
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Affects Versions: 8.0.1
> Reporter: Carl Boettiger
> Priority: Major
>
> If a user has set the AWS_DEFAULT_REGION, there is no way we can override
> that setting (especially to a null value) in a one-off call. Consider the
> following example. This fails:
> {code:java}
> library(arrow)
> Sys.setenv(AWS_DEFAULT_REGION="data")
> noaa <- s3_bucket("neon4cast-drivers/",
> endpoint_override = "data.ecoforecast.org",
> anonymous = TRUE) {code}
> If the env var is not set or unset, this succeeds. However, attempting to
> override the region does not help:
> {code:java}
> noaa <- s3_bucket("neon4cast-drivers/",
> endpoint_override = "data.ecoforecast.org",
> region = "us-east-1",
> anonymous = TRUE) {code}
> (nor does it help to set the region to "", or NULL. – note this is a MINIO
> host and so region is not needed anyway).
> Relatedly, one might expect that AWS_S3_ENDPOINT could be used instead of
> setting `endpoint_override`, but this does not seem to work either (lemme
> know if you want that in a separate issue thread). At least on the plus
> side, the above code does not fail if AWS_S3_ENDPOINT is set to some other
> value than given in endpoint_override, so that is nice).
