-----------------------------------------
Assignee: Tejaskriya Madhan
> S3G: Upload with Content-Type: plain/text; charset=utf-8 header will fail
> -------------------------------------------------------------------------
>
> Key: HDDS-5271
> URL: https://issues.apache.org/jira/browse/HDDS-5271
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode, S3
> Affects Versions: 1.1.0
> Reporter: Kohei Sugihara
> Assignee: Tejaskriya Madhan
> Priority: Major
> Attachments: s3g.log, upload.go
>
>
> Upload content via S3 gateway with "Content-Type: plain/text; charset=utf-8"
> header will fail with 500 code. At the same time, "Content-Type: plain/text"
> (without charset) and "Content-Type: plain/text; charset=UTF-8" (in
> uppercase) were accepted.
> We're running the official Ozone v1.1.0 release.
> These lines shown as below are known behavior:
> * 'text/plain' ==> OK
> * 'text/plain; charset=UTF-8' ==> OK
> * 'text/plain; charset=utf-8' ==> 500
> * 'text/html; charset=UTF-8' ==> OK (same as text/plain case)
> * 'text/html; charset=utf-8' ==> 500 (same as text/plain case)
> * 'text/markdown; charset=UTF-8' ==> OK
> * 'text/markdown; charset=utf-8' ==> OK
> I've attached a code snippet (upload.go) and a log from S3 gateway (s3g.log).
> This code can run easily with following command lines.
> {code:none}
> % go run upload.go --contenttype='text/plain; charset=utf-8'
> text/plain; charset=utf-8
> InternalServerError: Internal Server Error
> status code: 500, request id: , host id: exit status 1
> % go run upload.go --contenttype='text/plain; charset=UTF-8'
> text/plain; charset=UTF-8
> &\{http://example.com/<BUCKET>/<KEY> <nil> <nil>}%
> {code}
> HTTP request from upload.go is here:

> h2. Investigation
> We thought the issue is similar to HDDS-4856 but this issue will happen when
> empty Content-Type header was given. Our facing problem will appear when
> Content-Type defined together with the charset directive.
> The stack trace of S3 gateway indicates the request proceeded to remote
> invocation and failed with authentication error with
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken).
> There are many parts to preprocess a request before reaching RPC Client, so
> I suspect some Java servlet filters like ozone.s3.HeaderPreprocessor and
> hdds.server.http.NoCacheFilter. But as far as I found out, these are not a
> cause of this problem directly (because these are almost for generating
> response header). I also suspected some components like OzoneClientProducer,
> Signature Processor and HeaderPreprocessor. I think this is not direct cause.
> How do I investigate this problem in more detail?
