            <title>[SERVER-46040] moveChunk in multi_stmt_txn_jscore_passthrough_with_migration can cause failures when mongos retries commands that are not idempotent</title>
                <link>https://jira.mongodb.org/browse/SERVER-46040</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;An example scenario with dropIndex with 2+ shards:&lt;/p&gt;

&lt;p&gt;1. test sends dropIndex to mongos.&lt;br/&gt;
2. dropIndex successfully runs in shard0.&lt;br/&gt;
3. dropIndex returns StaleConfig error in shard1 because of migration.&lt;br/&gt;
4. Mongos retries dropIndex but got index does not exist error because it is already dropped in shard0.&lt;/p&gt;</description>

                            <comment id="2961724" author="jack.mulrow" created="Tue, 10 Mar 2020 19:07:21 +0000"  >&lt;p&gt;dropIndexes on mongos already considers IndexNotFound an &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ac3a2126fa/src/mongo/s/cluster_commands_helpers.cpp#L436&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ignorable error&lt;/a&gt; when &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ac3a2126fa/src/mongo/s/commands/cluster_drop_indexes_cmd.cpp#L95&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;aggregating shard responses&lt;/a&gt;, but the problem here is the helper dropIndexes uses will &lt;b&gt;not&lt;/b&gt; ignore an ignorable error &lt;a href=&quot;https://github.com/mongodb/mongo/blob/ac3a2126fa/src/mongo/s/cluster_commands_helpers.cpp#L490-L494&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;if it&apos;s reported by every shard&lt;/a&gt;, like in this case after the StaleConfig retry.&lt;/p&gt;

&lt;p&gt;One way to fix this could be to make mongos dropIndexes somehow &quot;remember&quot; if a shard successfully dropped the index across StaleConfig retries, so it knows it&apos;s safe to ignore IndexNotFound even if every shard returns it on a later attempt.&lt;/p&gt;</comment>
