We fail if the out option does not have the type of out in the first position:
> db.foo.mapReduce(map2,red2,{out:{replace:"shTest",db:"newdb", sharded:true}})
2014-08-25T11:22:26.173-0400 map reduce failed:{
"code" : 13297,
"ok" : 0,
"errmsg" : "exception: error creating initial database config information :: caused by :: can't have 2 databases that just differ on case have: newDB want to add: newdb"
} at src/mongo/shell/collection.js:1224
> db.foo.mapReduce(map2,red2,{out:{replace:"shTest",db:"newDB", sharded:true}})
// works
That was 2.4.8
In 2.6 it fails instead with:
> db.foo.mapReduce(map2,red2,{out:{db:"newDB", replace:"shTest",sharded:true}})
