> [Evgeny Salnikov noted this problem on the mailing list|http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201307.mbox/%3CCADz7Cx6PbMxExhb8gsCu9%3DP6nphJd2fYayov_%3D%3D%2Bo1sEXswWLw%40mail.gmail.com%3E], although the initial report was somewhat convoluted by suspicious description of adding shards after the fact.
> Steps to reproduce using 4.3.1 example...
> * startup a 2 node SolrCloud cluster following the "Example A" description on the SolrCloud wiki...
> ** cp example example2
> ** cd example && java -Dbootstrap_confdir=./solr/collection1/conf -Dcollection.configName=myconf -DzkRun -DnumShards=2 -jar start.jar
> ** cd example2 && java -Djetty.port=7574 -DzkHost=localhost:9983 -jar start.jar
> * index exactly one doc (to ensure that subsequent distributed queries get results from only one node)
> ** java -jar post.jar utf8-example.xml
> * execute a request using group.query
> ** http://localhost:7574/solr/select?q=*:*&group=true&group.query=cat:software
> stack trace...
