> As far as I could tell, this should not happen because some code in Hive
> iterates this list in parallel with names, assuming each ID will correspond
> to a name; however, I've seen it in some logs recently. Either names also
> contain duplicates and we should remove the line, or something could be
> broken. Could also be different for different operators? No idea.
