---------------------------------
Summary: Implement HeadObject REST endpoint
Key: HDDS-517
URL: https://issues.apache.org/jira/browse/HDDS-517
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Elek, Marton
The HEAD operation retrieves metadata from an object without returning the
object itself. This operation is useful if you are interested only in an
object's metadata. To use HEAD, you must have READ access to the object.
Steps:
1. Look up the volume
2. Read the key and return to the user.
The AWS reference is here:
https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectHEAD.html
We have a simple version of this call in HDDS-444 but without Range support.
