Release Note:
HIVE-195. Map-side join. (Namit Jain via zshao)
map-side joins are not supported.
If all the tables but one are small and can fit in memory, the join should be performed on the map-side. Ideally, it should be all cost-based, but
to start with, the user should be given an option to specify that he needs a map-side join.
