Daryn Sharp commented on HDFS-13489:
------------------------------------
On further inspection, this method appears to possibly be at odds with the
semantics of {{getSnapshottableDirListing}}. That method returns only the
snapshottable directories owned by the user. I don't know if there's perceived
security value in not letting a non-owner detect snapshot roots but someone
with snapshot expertise should comment.
Otherwise why not have the client call {{getSnapshottableDirListing}} and
prefix match against the given path?

> Currently, hdfs only lists the snapshotable paths in the filesystem. This
> feature would add the functionality of figuring out if a given path is
> snapshotable or not. If yes, it would return the base snapshotable path.
