Marius Grama commented on SOLR-8851: ------------------------------------ The only place I see that ExitingReaderException is being thrown is in the {{ExitableDirectoryReader.ExitableTermsEnum}} class. I could reproduce the {{ExitableDirectoryReader.ExitingReaderException}} in the class {{SearchHandler}} by using the following query : http://localhost:8983/solr/techproducts/terms?terms.fl=name&timeAllowed=1 In this case, the call {{rb.rsp.getValues().get("response")}} returns {{null}} reason why the variable {{r}} of type {{SolrDocumentList}} will be explicitly instantiated and the issue reported by you doesn't occur. On the other hand, I see in the {{QueryComponent}} class that an object instance of type {{ResultContext}} is used for "response" {code} ResultContext ctx = new ResultContext(); ctx.docs = rb.getResults().docList; ctx.query = rb.getQuery(); rsp.add("response", ctx); {code} , so the code line SearchHandler.java 293 is not quite correct : {code} SolrDocumentList r = (SolrDocumentList) rb.rsp.getValues().get("response"); {code} Could you give me a concrete solr query for reproducing the issue? > ClassCastException in SearchHandler > ----------------------------------- > > Key: SOLR-8851 > URL: https://issues.apache.org/jira/browse/SOLR-8851 > Project: Solr > Issue Type: Bug > Affects Versions: 5.4.1 > Reporter: Pascal Chollet > > When there is a query timeout in non-distrub mode, {{SearchHandler}} is > throwing a {{ClassCastException}}: > {code}java.lang.ClassCastException: org.apache.solr.response.ResultContext > cannot be cast to org.apache.solr.common.SolrDocumentList > at > org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:293) > at > org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:156) > ...{code} > The problem can be reproduced if any component running after > {{QueryComponent}} times out - in our case it is {{FacetComponent}} which > throws a {{ExitingReaderException}}. > {{SearchHandler:293}} expects a {{SolrDocumentList}} in {{rsp.response}}, but > {{QueryComponent}} did add a {{ResultContext}} instead. > It looks like this is not a problem, if the {{QueryComponent}} itself is > timing out, as rsp.response is null in that case.
