Colin Patrick McCabe commented on HADOOP-9912:
----------------------------------------------
Agree with Binglin that we don't want to follow symlinks in listStatus. In
general, I'd like to avoid changing HDFS or LocalFileSystem semantics at all.
I also would like to avoid having LocalFileSystem semantics diverge from HDFS.
Does a webex on Friday (Sep 6) sound good? If so, I will set up a dial-in
number and post it here.
My suggestion for Pig would be to simply follow symlinks in Pig whenever you
find them. That is, if {{FileStatus#isSymlink}} is true, call
{{FileSystem#getFileStatus}} on the path to get the target. That should work
on both the new and old Hadoop, and require no other changes. (Unless there's
something I'm missing here, which is possible...)
