Hello team, I have two tables A and B. A has 360Million rows with one column K. B has around two billion rows with multiple columns including K.
Both tables are clustered and sorted by K and Bucketed into same number of buckets. When I perform a join, I assumed there won't be any reducers spawned as the join would happen on map side. Still user fee reducers getting spawned. Any role for reducers here? Am I missing something? Sent from my iPhone
