> When I run the IContract* unit tests from s3a adapter to test our s3 gateway I found that some of the unit tests (such as {color:#000000}ITestS3AContractGetFileStatus{color}.testListStatusEmptyDirectory) fails with org.apache.hadoop.fs.s3a.AWSBadRequestException.
> Checking the request/response I found that the multi delete request (POST to the bucket address with ending with ?delete) fails with HTTP 400 and without any error in the logs.
> The multi delete endpoint was tested with the robot tests and it worked well with aws s3 cli:
> {code:java}
> aws s3api --endpoint http://localhost:9878 delete-objects --bucket buckettest --delete 'Objects=[{Key=multidelete/f1},{Key=multidelete/f2},{Key=multidelete/f4}]'{code}
> After some more investigation I found that the XML namespace was missing from the request:
> The request was something like this:
> {code:java}
> <Delete><Object><Key>multidelete/f1</Key></Object><Object><Key>multidelete/f2</Key></Object><Object><Key>multidelete/f4</Key></Object></Delete>{code}
> Instead of this:
> {code:java}
> <Delete xmlns="http://s3.amazonaws.com/doc/2006-03-01/"><Object><Key>multidelete/f1</Key></Object><Object><Key>multidelete/f2</Key></Object><Object><Key>multidelete/f4</Key></Object></Delete>{code}
> I believe the right approach is to add the namespace to request as it's documented by the AWS documentation but it seems s3a adapter doesn't do it and s3 accepts it.
> We need a custom jaxb unmarshaller logic for the multi delete requests to accept requests both with and without namespaces.
