Jason Lowe commented on HADOOP-9912:
------------------------------------

+1 for a Friday webex.

The main issue with listStatus not following symlinks is that all directory walkers written for FileSystem must make the change suggested for Pig above.  It's not just a Pig issue, it's an issue for any code written for FileSystem that expects to walk a directory tree.  listStatus is not just readdir, it's readdir *and* stat.  It's the stat that's messing things up, because it's acting like an lstat when most code is expecting stat.
