LiXin Ge commented on HDDS-517: ------------------------------- Upload the initial patch: 1. The treatment of exceptions is temporary, will come back to optimize it after HDDS-560 is merged. 2.Range retrieval requests is not fully supported in this patch, because our ClientProtocol of Ozone haven't support range read. > 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 > Assignee: LiXin Ge > Priority: Major > Labels: newbie > Attachments: HDDS-517.000.patch > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
