@steveloughran discovered completely by accident, but it's something to do
with the checksumming code.
If you comment out these lines:
```
// builder.addPlugin(LegacyMd5Plugin.create());
// do not do request checksums as this causes third-party store problems.
//
builder.requestChecksumCalculation(RequestChecksumCalculation.WHEN_REQUIRED);
// response checksum validation. Slow, even with CRC32 checksums.
// if (parameters.isChecksumValidationEnabled()) {
//
builder.responseChecksumValidation(ResponseChecksumValidation.WHEN_SUPPORTED);
// }
```
the test will pass. Could be something to do with s3Express not supporting
md5, will look into it.

> Project: Hadoop Common
> Issue Type: Improvement
> Components: build, fs/s3
> Affects Versions: 3.5.0
> Reporter: Steve Loughran

> Priority: Major
> Labels: pull-request-available
>
> Upgrade to a recent version of 2.33.x or later while off the critical path of
> things.
> HADOOP-19485 froze the sdk at a version which worked with third party stores.
> Apparently the new version works; early tests show that Bulk Delete calls
> with third party stores complain about lack of md5 headers, so some tuning is
> clearly going to be needed.
