Jason Lowe commented on HADOOP-9912:
------------------------------------
bq. In HDFS, listStatus only transparently resolves symlinks in the input path.
It doesn't resolve the results of the listing, and this is the correct behavior.
Isn't that going to break clients who are not symlink-aware? That means we
can't have a tree of files with a symlink to a directory in it. A
symlink-unaware tree walker client will not realize that the symlink is
actually pointing to a directory and should be traversed since the file status
will say it's not a directory. That's what's happening with Pig now. Aren't
there separate calls if one wants to know the true details of a link rather
than what the link references?
> globStatus of a symlink to a directory does not report symlink as a directory
