            <title>[SERVER-28874] make stale shardVersion error override &apos;allowPartialResults&apos; option in establishCursors()</title>
                <link>https://jira.mongodb.org/browse/SERVER-28874</link>

                    <description>&lt;p&gt;We should add &quot;&lt;tt&gt;!ErrorCodes::isStaleShardingError() &amp;amp;&amp;amp;&lt;/tt&gt;&quot; when checking whether to discard an error from a shard because of the allowPartialResults flag.&lt;/p&gt;

&lt;p&gt;This bug also exists in the ARM on 3.4 (although in 3.4, we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.4.4-rc0/src/mongo/s/query/async_results_merger.cpp#L495-L540&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;didn&apos;t swallow retriable errors&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;Also, should we really swallow all other errors? The only other error we check for on both &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.4.4-rc0/src/mongo/s/query/async_results_merger.cpp#L453-L484&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;3.4&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.5.6/src/mongo/s/query/establish_cursors.cpp#L88&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;3.6&lt;/a&gt; is ErrorCodes::CommandOnShardedViewNotSupportedOnMongod.&lt;/p&gt;</description>

&lt;p&gt;This ticket adds a js test case that aggregation fails if &apos;allowPartialResults&apos; is passed in the command, and the test case can be removed when we decide to officially support aggregation with allowPartialResults.&lt;/p&gt;
