            <title>[SERVER-34539] Re-enable sharded mapReduce concurrency testing and only use a single mongos</title>
                <link>https://jira.mongodb.org/browse/SERVER-34539</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Concurrent sharded mapReduce testing was disabled as part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-20057&quot; title=&quot;Concurrent, sharded mapReduces can fail when temporary namespaces collide across mongos processes&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-20057&quot;&gt;&lt;del&gt;SERVER-20057&lt;/del&gt;&lt;/a&gt;. However, it appears the bug in this ticket only occurs when there are multiple mongoses. I believe this testing should be re-enabled, but only use one mongos, since there may be other concurrent sharded mapReduce related issues, such as &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-33538&quot; title=&quot;mapReduce &amp;quot;replace&amp;quot; on a sharded output collection can lead to UUIDCatalog inconsistencies&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-33538&quot;&gt;&lt;del&gt;SERVER-33538&lt;/del&gt;&lt;/a&gt;, that can be found from this test coverage.&lt;/p&gt;</description>
