Hey, this is Michael, who was having the exact error on the Jetty side with an update. I've upgraded jetty from the 4.5.1 embedded version (in the example directory) to version 9.0.6, which means I had to upgrade my OpenJDK from 1.6 to 1.7.0_45. Also, I added the suggested (very large) settings to my solrconfig.xml:
<requestParsers enableRemoteStreaming="true" formdataUploadLimitInKB="2048000" multipartUploadLimitInKB="2048000" /> but I am still getting the errors when I put a second server in the cloud. Single servers (external zookeeper, but no cloud partner) works just fine. I suppose my next step is to try Tomcat, but according to your post, it will not help! Any help is appreciated, M. ----- Original Message ----- From: "Sai Gadde" <gadde....@gmail.com> To: solr-user@lucene.apache.org Sent: Monday, October 28, 2013 7:10:41 AM Subject: Solr 4.5.1 replication Bug? "Illegal to have multiple roots (start tag in epilog?)." we have a similar error as this thread. http://www.mail-archive.com/solr-user@lucene.apache.org/msg90748.html Tried tomcat setting from this post. We used exact setting sepecified here. we merge 500 documents at a time. I am creating a new thread because Michael is using Jetty where as we use Tomcat. formdataUploadLimitInKB and multipartUploadLimitInKB limits are set to very high value 2GB. As suggested in the following thread. https://issues.apache.org/jira/browse/SOLR-5331 We use out of the box Solr 4.5.1 no customization done. If we merge documents via SolrJ to a single server it is perfectly working fine. But as soon as we add another node to the cloud we are getting following while merging documents. This is the error we are getting on the server (10.10.10.116 - IP is irrelavent just for clarity)where merging is happening. 10.10.10.119 is the new node here. This server gets RemoteSolrException shard update error StdNode: http://10.10.10.119:8980/solr/mycore/:org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Illegal to have multiple roots (start tag in epilog?). at [row,col {unknown-source}]: [1,12468] at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:425) at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:180) at org.apache.solr.update.SolrCmdDistributor$1.call(SolrCmdDistributor.java:401) at org.apache.solr.update.SolrCmdDistributor$1.call(SolrCmdDistributor.java:1) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) On the other server 10.10.10.119 we get following error org.apache.solr.common.SolrException: Illegal to have multiple roots (start tag in epilog?). at [row,col {unknown-source}]: [1,12468] at org.apache.solr.handler.loader.XMLLoader.load(XMLLoader.java:176) at org.apache.solr.handler.UpdateRequestHandler$1.load(UpdateRequestHandler.java:92) at org.apache.solr.handler.ContentStreamHandlerBase.handleRequestBody(ContentStreamHandlerBase.java:74) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:135) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1859) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:703) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:406) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:195) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:222) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:123) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:171) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:936) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1004) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:589) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:310) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: com.ctc.wstx.exc.WstxParsingException: Illegal to have multiple roots (start tag in epilog?). at [row,col {unknown-source}]: [1,12369] at com.ctc.wstx.sr.StreamScanner.constructWfcException(StreamScanner.java:630) at com.ctc.wstx.sr.StreamScanner.throwParseError(StreamScanner.java:461) at com.ctc.wstx.sr.BasicStreamReader.handleExtraRoot(BasicStreamReader.java:2155) at com.ctc.wstx.sr.BasicStreamReader.nextFromProlog(BasicStreamReader.java:2070) at com.ctc.wstx.sr.BasicStreamReader.nextFromTree(BasicStreamReader.java:2647) at com.ctc.wstx.sr.BasicStreamReader.next(BasicStreamReader.java:1019) at org.apache.solr.handler.loader.XMLLoader.processUpdate(XMLLoader.java:213) at org.apache.solr.handler.loader.XMLLoader.load(XMLLoader.java:174) ... 22 more We tried with 4.5.0 first and then with 4.5.1 later. Both produce exact same error. Any ideas regarding how to resolve this? or is this a bug? Looks like it is a common error as it affects cloud setup and there must a workaround but we cannot figure it out. Any help appreciated. Thanks in advance Sai
