ASF GitHub Bot updated HDDS-4193: --------------------------------- Labels: pull-request-available (was: ) > Range used by S3 MultipartUpload copy-from-source should be inclusive > --------------------------------------------------------------------- > > Key: HDDS-4193 > URL: https://issues.apache.org/jira/browse/HDDS-4193 > Project: Hadoop Distributed Data Store > Issue Type: Bug > Reporter: Marton Elek > Assignee: Marton Elek > Priority: Blocker > Labels: pull-request-available > > S3 API provides a feature to copy a specific range from an existing key. > Based on the documentation, this range definitions is inclusive: > https://docs.aws.amazon.com/cli/latest/reference/s3api/upload-part-copy.html > {quote} > -copy-source-range (string) > The range of bytes to copy from the source object. The range value must > use the form bytes=first-last, where the first and last are the zero-based > byte offsets to copy. For example, bytes=0-9 indicates that you want to copy > the first 10 bytes of the source. You can copy a range only if the source > object is greater than 5 MB. > {quote} > But as it's visible from our [robot test|http://example.com], in our case we > use exclusive range: > {code} > upload-part-copy ... --copy-source-range bytes=0-10485758 > upload-part-copy ... --copy-source-range bytes=10485758-10485760 > {code} > Based on this AWS documentation it will return with a (10485758 + 1) + 3 > bytes long key, which is impossible if our original source key is just > 10485760. > I think the right usage to get the original key is the following: > {code} > upload-part-copy ... --copy-source-range bytes=0-10485757 > upload-part-copy ... --copy-source-range bytes=10485758-10485759 > {code} > (Note, this bug is found with the script in HDDS-4194, which showed that AWS > S3 is working in different way). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: ozone-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: ozone-issues-h...@hadoop.apache.org
