Isabelle Giguere updated SOLR-8319: ----------------------------------- Attachment: SOLR-8319-1.patch > NPE when creating pivot > ----------------------- > > Key: SOLR-8319 > URL: https://issues.apache.org/jira/browse/SOLR-8319 > Project: Solr > Issue Type: Bug > Reporter: Neil Ireson > Priority: Major > Attachments: SOLR-8319-1.patch, SOLR-8319.patch > > Time Spent: 10m > Remaining Estimate: 0h > > 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 is 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 (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
