> HADOOP-4044 introduces symbolic links in HDFS. That patch has some unit tests associated with it. The aim of this JIRA is to add more unit tests (including negative tests):
> deleting a symlink that points to a file
> deleting a symlink that points to a directory
> symlink to a symlink
> any test cases with relative links
> delete linked to file, but not link, access link
> delete linked to file, recreate the same file, access link
> links to other filesystems
> archives containing links
> rename a file to an existing symlink
> rename a symlink to an existing file
> setTimes and setReplication cases should check the result on both the symlink and linked to file
> tests involving lack of permissions to create symlinks
> tests that try to createSymlinks with filesystems that don't support them
> ...
