             Summary: Implement CopyObject REST endpoint
                 Key: HDDS-516
                 URL: https://issues.apache.org/jira/browse/HDDS-516
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Elek, Marton


The Copy object is a simple call to Ozone Manager.  This API can only be done after the PUT OBJECT Call.

This implementation of the PUT operation creates a copy of an object that is already stored in Amazon S3. A PUT copy operation is the same as performing a GET and then a PUT. Adding the request header, x-amz-copy-source, makes the PUT operation copy the source object into the destination bucket.

If the Put Object call has this header, then Put Object call will issue a rename. 

Work Items or JIRAs
Detect the presence of the extra header - x-amz-copy-source
Make sure that destination bucket exists.

The AWS reference is here:

https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html

(This jira is marked as newbie as it requires only basic Ozone knowledge. If somebody would be interested, I can be more specific, explain what we need or help).
