            <title>[SERVER-899] mapReduce fails on large sharded collection</title>
                <link>https://jira.mongodb.org/browse/SERVER-899</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The following mapReduce runs successfully on a smaller collection in the same sharded db or on the same collection but on a non-sharded DB.&lt;/p&gt;

&lt;p&gt;--------------------------------------------------------------------------------&lt;/p&gt;

&lt;p&gt;&amp;gt; $mapv = function () &lt;/p&gt;
{ emit(this.v, 1); }
&lt;p&gt;function () {&lt;br/&gt;
    emit(this.v, 1);&lt;br/&gt;
}&lt;br/&gt;
&amp;gt; $reducev = function ($vis_id, $counts) { var $count = 0; $counts.forEach(function ($c) {$count += $c;}); return $count; }&lt;br/&gt;
function ($vis_id, $counts) {&lt;br/&gt;
    var $count = 0;&lt;br/&gt;
    $counts.forEach(function ($c) {$count += $c;});&lt;br/&gt;
    return $count;&lt;br/&gt;
}&lt;br/&gt;
&amp;gt; $resv = db.vis1.mapReduce( $mapv, $reducev, { query : &lt;/p&gt;
{ p : &apos;78053631&apos; }
&lt;p&gt; } );&lt;br/&gt;
Fri Jan  8 12:54:08 JS Error: uncaught exception: map reduce failed: final reduce failed: &lt;/p&gt;

&lt;p&gt;exhibit-a.pl starts a single mongod process, loads the db dump and successfully executes a mapreduce command, then prints a report.&lt;/p&gt;

&lt;p&gt;exhibit-b.pl starts and configures a sharded setup, load the db dump and unsuccessfully executes a mapreduce command, dying with:&lt;/p&gt;
