> Project: Hadoop Common
> Issue Type: Bug
> Components: viewfs
> Reporter: Gera Shegalov
> Assignee: Gera Shegalov
> Priority: Blocker
> Fix For: 3.0.0, 2.4.0

> Attachments: HADOOP-10191.v01.patch

>
> ViewFileSystem allows 1) unconditional listing of internal directories (mount
> points) and 2) and changing work directories.
> 1) requires read permission
> 2) requires executable permission
> However, the hardcoded PERMISSION_RRR == 444 for FileStatus representing an
> internal dir does not have executable bit set.
> This confuses YARN localizer for public resources on viewfs because it
> requires executable permission for "other" on all of the ancestor directories
> of the resource.
> {code}
> java.io.IOException: Resource viewfs:/pubcache/cache.txt is not publicly
> accessable and as such cannot be part of the public cache.
