             Summary: fl renaming of uniqueKey field generates null pointer exception in SolrCloud configuration
                 Key: SOLR-6744
                 URL: https://issues.apache.org/jira/browse/SOLR-6744
             Project: Solr
          Issue Type: Bug
          Components: SolrCloud
    Affects Versions: 4.10.1
         Environment: Multiple replicas on SolrCloud config.  This specific example with 4 shard, 3 replica per shard config.  This bug does NOT exist when query is handled by single core.

            Priority: Minor


If trying to rename the uniqueKey field using 'fl', and sending the query to SolrCloud config, a null pointer exception gets generated.
