Description
For mappers with side-effects, or mappers that work as aggregators (i.e. no output on individual key-value pairs, but an aggregate output at the end of all key-value pairs), output should be performed in the close method. For this purpose, we need to supply output collector and reporter to the close method of Mapper. This involves interface change, though. Thoughts ?
