            <title>[SERVER-7926] Map Reduce with sharded output can apply reduce on duplicate documents if a migration happened</title>
                <link>https://jira.mongodb.org/browse/SERVER-7926</link>

                    <description>&lt;p&gt;Buildbot failure:&lt;/p&gt;

&lt;p&gt;If a migration happened on the map reduce job output collection right before the mapreduce.shardedfinish is called, there is a possibility that one of the shard still thinks he owns the chunk, whereas it has already donated it to another shard.&lt;/p&gt;</description>

The timestamps for the moveChunks were before the drop collection command so they should have been deleted. Have to dig further. I also found a very easy way to make the test fail, by simply adding these lines in the test:&lt;/p&gt;

&lt;p&gt;1. Drop output collection on shard0.&lt;br/&gt;
2. Balancing round move chunks from shard1 to shard0 &amp;lt;---- // balancer is adding new docs to shard0!!!!&lt;br/&gt;
3. Drop output collection on shard1.&lt;br/&gt;
4. Proceed...&lt;/p&gt;

&lt;p&gt;Note: the chunks being moved in step#2 are from the output of the previous iteration.&lt;/p&gt;
