Fix Version/s: (was: 1.4.0)
> [FSO] S3G folder support fso layout filestatus s3A compatibility
> ----------------------------------------------------------------
>
> Key: HDDS-7922
> URL: https://issues.apache.org/jira/browse/HDDS-7922
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Neil Joshi
> Assignee: Mladjan Gadzic
> Priority: Major
> Labels: pull-request-available
> Attachments: FSO S3G folder support - s3A compatibility for
> filestatus HEAD requests and GET .png
>
>
> Currently there exists an incompatibility with file stats issued with s3a
> adapter through s3-gateway on directories created with fso layout.
> S3a expects file status (exist) queries on directories issued through s3
> gateway to have path names ending with a '/' slash. The s3gateway returns
> directory exists on directory paths with and without a trailing slash due to
> internal path normalization (eg. path/dir1 == path/dir1/).
>
> File exists, file status is queried by s3A over s3gateway with Head requests
> (head-object s3 requests). Proposed is an implementation to resolve the
> issue and to cover corner cases to support fso folders over s3g by modifying
> the s3g ObjectEndpoint to check whether the requested path is a directory, if
> so, to only return ok if path has trailing '/'. This would support s3 Head
> requests and Get requests. The type of object, where file or directory is
> determined in the head-object and get-object request through checking the
> keyInfo (modifying the OzoneKey and OzoneKeyDetails) isFile().
>
> A sample sequence diagram for this is attached.
