> 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).
