Neil Ireson created SOLR-8319: --------------------------------- Summary: NPE when creating pivot Key: SOLR-8319 URL: https://issues.apache.org/jira/browse/SOLR-8319 Project: Solr Issue Type: Bug Reporter: Neil Ireson
I get a NPE, the trace is shown at the end. The problem seems to be this line in the getSubset method: Query query = ft.getFieldQuery(null, field, pivotValue); Which takes a value from the index and then analyses it to create a query. I believe the problem is that when my analysis process is applied twice it results in a null query. OK this might be seen as my issue because of dodgy analysis, I thought it might be because I have the wrong order with LengthFilterFactory before EnglishPossessiveFilterFactory and KStemFilterFactory, i.e.: <filter class="solr.LengthFilterFactory" min="3" max="32"/> <filter class="solr.EnglishPossessiveFilterFactory"/> <filter class="solr.KStemFilterFactory"/> So that "cat's" -> "cat" -> "", however any filter order I tried still resulted in a NPE, and perhaps there is a viable case where parsing a term twice results in a null query. The thing is I don't see why when the query term comes from the index it has to undergo any analysis. If the term if from the index can it not simply be created using a TermQuery, which I would imagine would also be faster. I altered the "getFieldQuery" line above to the following and that has fixed my NPE issue. Query query = new TermQuery(new Term(field.getName(), pivotValue)); So far this hasn't caused any other issues but perhaps that is due to my use of Solr, rather than actually fixing an issue. o.a.s.c.SolrCore java.lang.NullPointerException at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936) at org.apache.solr.util.ConcurrentLRUCache.get(ConcurrentLRUCache.java:91) at org.apache.solr.search.FastLRUCache.get(FastLRUCache.java:130) at org.apache.solr.search.SolrIndexSearcher.getDocSet(SolrIndexSearcher.java:1296) at org.apache.solr.handler.component.PivotFacetProcessor.getSubset(PivotFacetProcessor.java:375) at org.apache.solr.handler.component.PivotFacetProcessor.doPivots(PivotFacetProcessor.java:305) at org.apache.solr.handler.component.PivotFacetProcessor.processSingle(PivotFacetProcessor.java:228) at org.apache.solr.handler.component.PivotFacetProcessor.process(PivotFacetProcessor.java:170) at org.apache.solr.handler.component.FacetComponent.process(FacetComponent.java:262) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:277) 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
