Please let me know if more details are required.

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. But reducers getting spawned. Any role for reducers here? Am I missing something?
