Alan Burlison commented on HADOOP-12583:
----------------------------------------
Yes, that's what happens on Solaris because that's what POSIX says should
happen. The Linux default behaviour in not POSIX compliant, and tests which
assume the Linux default behaviour are incorrect.

> I'm not sure what the root cause is, most likely Linux-specific assumptions
> about how symlinks behave. Further investigation needed.
