Description
(I couldn't find a duplicate but this was a known issue - please duplicate if you know of one)
The 'system.js' collection is consulted locally on each shard, but there is no mechanism to ensure that its contents are identical on each shard. In order to use this correctly for a sharded collection, you have to directly connect to a shard and insert the same documents on each shard.
