Daryn Sharp commented on HADOOP-9912:
-------------------------------------
Jason makes an excellent point about how the crux of the problem is
{{listStatus}} combines both {{readdir}} + {{stat}}.
There may be another alternative to a new API call. I haven't thought it
through, but perhaps a middle-ground to address compatibility and to better
handle symlinks is to return the resolved link's file status but to set the
{{isLink}} bit in the status. This allows the extremely few use cases that
care about whether something is a symlink to call {{getFileLinkStatus}}. It's
an extra RPC, but probably 99% of the time the user doesn't care that something
is a symlink. The only "common" case is probably {{FSShell}} ls.
> globStatus of a symlink to a directory does not report symlink as a directory
