             Summary: SolrCloud can select a core not in active state for querying
                 Key: SOLR-8215
                 URL: https://issues.apache.org/jira/browse/SOLR-8215
             Project: Solr
          Issue Type: Bug
            Reporter: Varun Thacker


A query can be served by a core which is not in active state if the request hits the node which hosts these non active cores.

We explicitly check for only active cores to search against  in {{CloudSolrClient#sendRequest}} Line 1043 on trunk.

But we don't check this if someone uses the REST APIs 

{{HttpSolrCall#getCoreByCollection}} should only pick cores which are active on line 794 on trunk. 

We however check it on line 882/883 in HttpSolrCall, when we try to find cores on other nodes when it's not present locally.

So let's fix {{HttpSolrCall#getCoreByCollection}} to make the active check as well.
