      MapReduce would be more useful if it supports many collections as data source instead of just one. This feature would turn MongoDB into a full replacement for Hadoop in sharded environments, and will add capabilities to process largest amount of data.

      I think it would be even more useful if MapReduce can process collections from different databases as well, because the number of collections in a databases is limited by default.
