--------------------------------
[~sershe]: removed the extra config and defaults to synthetic file-ids if
file-id paths are disabled.
> LLAP: Force synthetic file-id for filesystems which have HDFS protocol impls
> with POSIX mutation semantics

> HDFS client protocol is not a guarantee of the immutability of files - the
> synthetic file-id includes the mtime of the file as well, which is a
> fail-safe for filesystems which implement the client wire protocol without
> offering the same storage side restrictions on immutability (i.e allow NFS
> read-write-modify on the backend).
