Doug Cutting commented on HADOOP-6427:
--------------------------------------
Symbolic links should be resolved relative to their source location. So
hdfs://x/foo - > /bar should be interpreted as a link to hdfs://x/bar. The
client should generally rewrite a symlink with new Path(src, dest) before
de-referencing it, assuming src is fully-qualified. Should we change the
accessor on FileStatus to do this, and perhaps add a getRawLink() method? I
think the primary path field of a FileStatus (src) is always absolute, no?

> The Path class has a method to make a path qualified but not to query if the
> path is qualified. This is needed for HADOOP-64221. In addition this patch
> adds tests to TestPath that cover the file scheme. Note that "fully
> qualified" applies to domain names not URIs so this function and it tests
> also serve to define what we mean by a fully qualified path.
