Colin Patrick McCabe commented on HDFS-7677:
--------------------------------------------
I think we should support this, just for consistency with the other operations.
But keep in mind that symlinks are hard-disabled in branch-2 because of
security and other issues, and that's probably not going to change any time
soon. See HADOOP-10019 for details.

> support it.
