Tsz Wo (Nicholas), SZE commented on HDFS-245:
---------------------------------------------

You may already have it: I think we need tests for cycles and different fil=
e system schemes, e.g.
{noformat}
  hdfs://namenode/foo/link1  (a symlink pointing to s3://hostname/bar)
  s3://hostname/bar/link2  (a symlink pointing to hdfs://namenode/foo)
{noformat}
Then, test various commands like ls, cp, distcp, etc.

> HDFS should support symbolic links. A symbolic link is a special type of =
file that contains a reference to another file or directory in the form of =
an absolute or relative path and that affects pathname resolution. Programs=
 which read or write to files named by a symbolic link will behave as if op=
erating directly on the target file. However, archiving utilities can handl=
e symbolic links specially and manipulate them directly.
