Hello, Trying to some tests with Hadoop 2.9 + Ceph S3(Jewel, 10.2.10) and ran into a multi-part uploading issue. It looks like the new S3a driver(aws-java-sdk-bundle-1.11.199.jar, v4 signature) in Hadoop is not compatible with Ceph S3(Jewel). I find there's a doc on S3 API support status, but lack of the corresponding S3 version info there. Is there any info on the detail supported version, v2 only? http://docs.ceph.com/docs/jewel/radosgw/s3/ I also find some commit to enable the V4 support here, I think this should be ready in Luminous? https://github.com/ceph/ceph/pull/15965/commits/82a7aa9e3eabfde4a82046d78aad2dadbfc0d8e1 Any comments would be appreciated!
