>
> Currently it is impossible to specify application level for files in
> distributed cache in YARN. For applications with big common data it is very
> crucial to have ability to share data only for application and not spam
> public cache. Moreover, public localiser is limited for parallel downloads,
> so applications with big caches affect application startup of other
> applications.
> Current logic is complicated and based on file permissions. Making proposed
> changes, user can override public level to any level (PUBLIC/APP/PRIVATE)
> without breaking anything, and even not need to bother with permission, if
> private cache is needed.
