>                 Key: HADOOP-14211
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14211
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: viewfs
>    Affects Versions: 2.6.0
>            Reporter: Erik Krogen
>            Assignee: Erik Krogen
>         Attachments: HADOOP-14211.000.patch
>
>
> Right now {{ChRootedFs}} passes the following up to the {{AbstractFileSystem}} superconstructor:
> {code}
>     super(fs.getUri(), fs.getUri().getScheme(),
>         fs.getUri().getAuthority() != null, fs.getUriDefaultPort());
> {code}
> This passes a value of {{authorityNeeded==true}} for any {{fs}} which has an authority,
but this isn't necessarily the case - ViewFS itself is an example of this. In fact you will
encounter this issue if you try to nest one ViewFS within another - I can't think of any reason
why you would want to do that but there's no reason why you shouldn't be able to and in general
ViewFS is making an assumption that it then proves invalid by its own behavior. The {{authorityNeeded}}
check isn't necessary in this case anyway; {{fs}} is already an instantiated {{AbstractFileSystem}}
which means it has already used the same constructor with the value of {{authorityNeeded}}
(and corresponding validation) that it actually requires.
