                Author: ASF GitHub Bot

    Worklog Time Spent: 10m 
      Work Description: elek commented on pull request #1278: HDDS-1950. S3 MPU 
part-list call fails if there are no parts
URL: https://github.com/apache/hadoop/pull/1278
 
 
   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.
