> 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.
