Larry McCay commented on KNOX-754:
----------------------------------
[~BigDataOrange] - I notice that you added ClientDSL as one of the components.
Did you happen to observe some issue with special characters from the client
side as well?
My suspicion is that this is a rewrite issue wrt Location header on the server
side.

> Key: KNOX-754
> URL: https://issues.apache.org/jira/browse/KNOX-754
> Project: Apache Knox
> Issue Type: Bug
> Components: ClientDSL, Server
> Affects Versions: 0.9.1
> Environment: Apache Knox 0.9.1, Apache Hadoop 2.7.2
> Reporter: Alexandre Linte
> Priority: Critical
> Fix For: 0.10.0
>
>
> Since Knox 0.9.1, Knox can't work with files which contain special characters
> as : é, ù, ü, è, etc... This is reproducible at 100%. It was working well
> with Knox 0.7.0 so it's a regression.
> This happens when doing a GET or a PUT of a file of this type, and more
> particularly at the "location" process of the request. You can find an
> example below:
