this is the default. why are you setting it again?

Review Comment:
1. junit assert equals has the order (expected, actual) for the error
messages to work
2. use AssertJ.assertThat() for new tests please -it's far more powerful.
while it takes a while to learn, smaller tests are the place to do it.

check your import rules. they MUST be

Review Comment:
move this to a constant in `org.apache.hadoop.fs.s3a.impl.InternalConstants`
and then you can reference it in tests.
> Fix S3A filesystem such that the scheme matches the URI scheme
> --------------------------------------------------------------
>
> Key: HADOOP-18684
> URL: https://issues.apache.org/jira/browse/HADOOP-18684
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 3.3.5
> Reporter: Harshit Gupta
> Priority: Major
> Labels: pull-request-available
>
> Certain codepaths use the FileContext API's to perform FS based operations
> such as yarn log aggregations. While trying to reuse the S3A connector for
> GCS based workloads the yarn log aggregation was not happening. Upon further
> investigation it was observed that FileContext API have hardcoded URI scheme
> checks that need to disabled/updated to make S3A compatible with non AWS
> stores.
