-------------------------------------

Hi Andrew, right now the DistributributedFileSystem and DFSClient both have the 
API that returns an array. I agree with you and if we proceed with your idea, 
should we deprecate these old API?

> Expose getSnapshottableDirListing as a public API in HdfsAdmin

> Found at HIVE-16294. We have a CLI API for listing snapshottable dirs, but no 
> programmatic API. Other snapshot APIs are exposed in HdfsAdmin, I think we 
> should expose listing there as well.
