question: public void queryAndCompareShards ( SolrParams params ) throws Exception { updateMappingsFromZk ( jettys , clients ) ; List < String > shards = new ArrayList < > ( shardToJetty . keySet ( ) ) ; for ( String shard : shards ) { queryAndCompareReplicas ( params , shard ) ; } }
target:  For each Shard, executes a query against each live and active replica of that shard and asserts that the results are identical for each replica of the same shard. Because results are not compared between replicas of different shards, this method should be safe for comparing the results of any query, even if it contains "distrib=false", because the replicas should all be identical.
