Terence Yim commented on TWILL-223:
-----------------------------------
With this enhancement, the same {{FileContextLocationFactory}} can be reused
for different user, hence allowing submitting application with different UGI
via the same {{TwillRunner}}.
> FileContextLocationFactory should use FileContext instance based on the
> caller UGI

>
> 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.
