DistributedFileSystem#getFileLinkStatus should not fully qualify the link target

    • Type: Bug

      Description

      The NN returns a FileStatus containing the exact link target as specified by the user at creation. However, DistributedFileSystem#getFileLinkStatus explicit overwrites the target with the fully scheme qualified path lookup. This causes multiple issues such as:

      1. Prevents clients from discerning if the target is relative or absolute
      2. Mangles a target that is not intended to be a path
      3. Causes incorrect resolution with multi-layered filesystems - ie. the link should be resolved relative to a higher level fs (ie. viewfs, chroot, filtered, etc)
