有人使用wpsolr和设置solr服务器有这种经验吗?我只是想知道如何解决此问题。
Solr HTTP错误:确定(500){“ responseHeader”:{“ status”:500,“ QTime”:0},“ error”:{“ trace”:“ java.lang.NullPointerException \ n \ tat org .apache.solr.update.processor.DistributedUpdateProcessor。(DistributedUpdateProcessor.java:322)\ n \ tat org.apache.solr.update.processor.DistributedUpdateProcessor。(DistributedUpdateProcessor.java:284)\ n \ tat org.apache.solr .update.processor.DistributedUpdateProcessorFactory.getInstance(DistributedUpdateProcessorFactory.java:61)\ n \ tat org.apache.solr.update.processor.DistributedUpdateProcessorFactory.getInstance(DistributedUpdateProcessorFactory.java:31)\ n \ tat org.apache.solr.update .processor.UpdateRequestProcessorChain.createProcessor(UpdateRequestProcessorChain.java:216)\ n \ tat org.apache.solr.handler.ContentStreamHandlerBase.handleRequestBody(ContentStreamHandlerBase.java:54)\ n \ tat org.apache.solr.handler.RequestHandlerBase.handleRequest (RequestHandlerBase.java:173)\n\t org.apache.solr.core.SolrCore.execute(SolrCore.java:2477)\ n \ t org.apache.solr.servlet.H ttpSolrCall.execute(HttpSolrCall.java:723)\ n \ tat org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:529)\ n \ tat org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchatchFilter。 java:361)\ n \ tat org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:305)\ n \ tat org.eclipse.jetty.servlet.ServletHandler $ CachedChain.doFilter(ServletHandler.java:1691) \ n \ tat org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:582)\ n \ tat org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143)\ n \ tat org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:548)\ n \ tat org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:226)\ n \ tat org.eclipse。 jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1180)\ n \ tat org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:512)\ n \ tat org.eclipse.jetty.server。 session.SessionHandler.doScope(SessionHandler.java:185)\ n \ t org.eclipse.jetty.ser ver.handler.ContextHandler.doScope(ContextHandler.java:1112)\ n \ tat org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141)\ n \ tat org.eclipse.jetty.server。 handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:213)\ n \ tat org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:119)\ n \ tat org.eclipse.jetty.server.handler HandlerWrapper.handle(HandlerWrapper.java:134)\ n \ tat org.eclipse.jetty.rewrite.handler.RewriteHandler.handle(RewriteHandler.java:335)\ n \ tat org.eclipse.jetty.server.handler.HandlerWrapper。 handle(HandlerWrapper.java:134)\ n \ tat org.eclipse.jetty.server.Server.handle(Server.java:534)\ n \ tat org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java: 320)\ n \ t org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:251)\ n \ tat org.eclipse.jetty.io.AbstractConnection $ ReadCallback.succeeded(AbstractConnection.java:273)\ n \ tat org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:95)\ n \ tat org.ecl ipse.jetty.io.SelectChannelEndPoint $ 2.run(SelectChannelEndPoint.java:93)\ n \ tat org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.executeProduceConsume(ExecuteProduceConsume.java:303)\ n \ tat org.eclipse .jetty.util.thread.strategy.ExecuteProduceConsume.produceConsume(ExecuteProduceConsume.java:148)\ n \ tat org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.run(ExecuteProduceConsume.java:136)\ n \ tat org .eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:671)\ n \ tat org.eclipse.jetty.util.thread.QueuedThreadPool $ 2.run(QueuedThreadPool.java:589)\ n \ tat java。 lang.Thread.run(Thread.java:748)\ n“,”代码“:500}}
