> During metadata gathering phase hive creates staging/scratch dir which is
> further used by FS op (FS op sets up staging dir within this dir for tasks to
> write to).
> Since FS op do mkdirs to setup staging dir we can skip creating scratch dir
> during metadata gathering phase. FS op will take care of setting up all the
> dirs.
