Elek, Marton created HDDS-1950:
----------------------------------
Summary: S3 MPU part list can't be called if there are no parts
Key: HDDS-1950
URL: https://issues.apache.org/jira/browse/HDDS-1950
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: S3
Reporter: Elek, Marton
If an S3 multipart upload is created but no part is upload the part list can't
be called because it throws HTTP 500:
Create an MPU:
{code}
aws s3api --endpoint http://localhost:9999 create-multipart-upload
--bucket=docker --key=testkeu
{
"Bucket": "docker",
"Key": "testkeu",
"UploadId": "85343e71-4c16-4a75-bb55-01f56a9339b2-102592678478217234"
}
{code}
List the parts:
{code}
aws s3api --endpoint http://localhost:9999 list-parts --bucket=docker
--key=testkeu
--upload-id=85343e71-4c16-4a75-bb55-01f56a9339b2-102592678478217234
{code}
It throws an exception on the server side, because in the
KeyManagerImpl.listParts the ReplicationType is retrieved from the first part:
{code}
HddsProtos.ReplicationType replicationType =
partKeyInfoMap.firstEntry().getValue().getPartKeyInfo().getType();
{code}
Which is not yet available in this use case.
