 Description   

Description

Downstream Change Summary

With this change, the mapReduce command will no longer return execution statistics as part of the command response object. Instead users will be requested to run mapReduce via explain command with executionStats.

As discussed with Jeff Yemin, this will break a method used by the legacy Java driver API to retrieve stats. It is possible that other drivers will be affected as well.

Description of Linked Ticket

These will be replaced by support for mapReduce explain with executionStats
