Issue Status as of May 27, 2014 ISSUE SUMMARY USER IMPACT WORKAROUNDS AFFECTED VERSIONS FIX VERSION RESOLUTION DETAILS Original DescriptionRun the map reduce example on a 2.6 replica set. From the oplog, I can see that mapReduce generates tmp collections <database.tmp.mr.collection_x_inc> without _id field. This would cause performance issue when it tried to replicate these tmp collections on the secondaries.
