> Add PathCapabilities to FS and FC to complement StreamCapabilities
> ------------------------------------------------------------------
>
> Key: HADOOP-15691
> URL: https://issues.apache.org/jira/browse/HADOOP-15691
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Attachments: HADOOP-15691-001.patch, HADOOP-15691-002.patch,
> HADOOP-15691-003.patch, HADOOP-15691-004.patch
>
>
> Add a {{PathCapabilities}} interface to both FileSystem and FileContext to
> declare the capabilities under the path of a filesystem through both the
> FileSystem and FileContext APIs
> This is needed for
> * HADOOP-14707: declare that a dest FS supports permissions
> * object stores to declare that they offer PUT-in-place alongside
> (slow-rename)
> * Anything else where the implementation semantics of an FS is so different
> caller apps would benefit from probing for the underlying semantics
> I know, we want all filesystem to work *exactly* the same. But it doesn't
> hold, especially for object stores —and to efficiently use them, callers need
> to be able to ask for specific features.
