Sergey Shelukhin commented on HIVE-5069:
----------------------------------------

Is modifying the map key inside SkewedColValueLocationMaps the only problem? If 
so, I wonder if the extra external map is necessary. Lists follow each other 
(SKEWED_STRING_LIST_VALUES.STRING_LIST_ID could be a added to the query as the 
2nd "order by" to make it certain), so we are always dealing with only one.

I am assuming the lists are not reused between SDs; the code implies they are 
not (it adds the element every time it's encountered from join).
