Vincent Cautaerts closed SOLR-8115. ----------------------------------- Resolution: Duplicate As Markus Jelsma noticed, this is a duplicate of SOLR7864. Sorry, I hadn't found it! Thanks, > On query timeout, casting error (...ResultContext cannot be cast to > ...SolrDocumentList) > ---------------------------------------------------------------------------------------- > > Key: SOLR-8115 > URL: https://issues.apache.org/jira/browse/SOLR-8115 > Project: Solr > Issue Type: Bug > Components: Server > Affects Versions: 5.3.1 > Environment: Ubuntu 14.04 with Java 1.8.0.60 > Using solR in non-distributed, non Cloud mode. > Reporter: Vincent Cautaerts > Priority: Minor > > When making a query, and hitting a timeout, solR throws an error > "org.apache.solr.response.ResultContext cannot be cast to > org.apache.solr.common.SolrDocumentList" > This is display in solrJ log files. No mention of a timeout can be seen here. > When searching in server log files, just before that error, I find this > message (WARN): > The request took too long to iterate over terms. > It seems that in case of an exception, the value of > rb.rsp.getValues().get("response"); > is not a SolrDocumentList, but a ResultContext. And therefore the cast at > line 297 of SearchHandler fails, and an erroneous error message (...) is > output. > the problem is not the timeout, but the fact that a timeout gives a casting > exception, instead of a timeout exeption. This makes finding the origin of > the problem hard (and impossible if looking only at the logs on the client > side). > Note: complete stack trace: > 2015-10-02 07:07:49,523 ERROR > [qtp1192108080-22][org.apache.solr.common.SolrException] (core.SolrCore:139) > - java.lang.ClassCastEx > ception: org.apache.solr.response.ResultContext cannot be cast to > org.apache.solr.common.SolrDocumentList > at > org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:297) > at > org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:143) > at org.apache.solr.core.SolrCore.execute(SolrCore.java:2068) > at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:669) > at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:462) > at > org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:214) > at > org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:179) > at > org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1652) > at > org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:585) > at > org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) > at > org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:577) > at > org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:223) > at > org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1127) > at > org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:515) > at > org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) > at > org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1061) > at > org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) > at > org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:215) > at > org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:110) > at > org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:97) > at org.eclipse.jetty.server.Server.handle(Server.java:499) > at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:310) > at > org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:257) > at > org.eclipse.jetty.io.AbstractConnection$2.run(AbstractConnection.java:540) > at > org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:635) > at > org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:555) > at java.lang.Thread.run(Thread.java:745) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
