Andrew Wang commented on HADOOP-9912:
-------------------------------------

I don't mind Daryn's proposal of a {{resolveLink}} flag defaulting to true for {{globStatus}} and {{listStatus}}. It's a little gross since (as Eli noted) Hadoop 2 GA APIs should all be symlink-aware by default (and we should be allowed to break compat here), but compatibility is compatibility.

However, I don't want the {{isSymlink}} bit being set for a resolved {{FileStatus}}, since isSymlink/isDir/isFile should be exclusive properties. There isn't much you can do with the knowledge a FileStatus was reached through a symlink. Symlink-aware clients will just use {{resolveLink=false}} and walk it properly themselves.
