> Project: Apache Twill
> Issue Type: Bug
> Reporter: Terence Yim
> Assignee: Terence Yim
> Fix For: 0.11.0
>
>
> The {{FileContextLocationFactory}} internally has a cached {{FileContext}}
> object that was created when the factory was created. However, when the
> {{getFileContext}} is called (directly or via one of those {{create}}
> methods), the UGI might be different then the cached one. If the cached one
> is returning, FS operations will be performed with the user who creates the
> factory, not the one who calls the {{create}} method.
