Zita Dombi updated HDDS-5828:
-----------------------------
Status: Patch Available (was: In Progress)
> [HTTPFSGW] Add proper handling for unsupported operations
> ---------------------------------------------------------
>
> Key: HDDS-5828
> URL: https://issues.apache.org/jira/browse/HDDS-5828
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: István Fajth
> Assignee: Zita Dombi
> Priority: Major
> Labels: pull-request-available
>
> As stated in the design doc, we need to address unsupported calls properly in
> HTTPFS GW. There is a default error handler, that handles queries that are
> supported by the HDFS NameNode but are not supported by the HDFS HTTPFSGW
> implementation, we can partly rely on that, but there are some operations
> that would require extra care.
> Relevant part of the design:
> Handling of unsupported calls
> For calls that we do not have support for in Ozone, HTTP 501 Not Implemented
> status code has to be returned. As described in
> [RFC2616|https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html] by the
> World Wide Web Consortium, this status code is the response to be given when
> "The server does not support the functionality required to fulfill the
> request. This is the appropriate response when the server does not recognize
> the request method and is not capable of supporting it for any resource."
> Handling of invalid operations on volumes or buckets
> For example file creation is not allowed by the ofs scheme on volume and
> bucket paths, these operations should return an HTTP 400 Bad Request status
> code, with a proper error message in the response body.
