Scott, I have no idea how these problems might be related. However, I think you can solve the problem with DIH not being able to find the primary key if you explicitly declare it by specifying the "pk" property on the parent entity.
<entity name="parent" pk="keyName" ... /> You might get more and better resonses to your solr-related question by posting to the solr-user list rather than the java-user list.

When someone in our CMS publishes an article, we have a listener that indexes it straight to solr. We use the previously instantiated HttpSolrServer, build the solr document, add it with server.add(doc) .. then do a server.commit() right away. This works fine, except that meanwhile, another process is importing new data from an SQL db into the same core. For some reason, sometimes this process errors: Feb 26, 2013 3:05:03 PM org.apache.solr.handler.dataimport.DataImporter doDeltaImport SEVERE: Delta Import Failed java.lang.RuntimeException: java.lang.IllegalArgumentException: deltaQuery has no column to resolve to declared primary key pk='id' at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:273) at org.apache.solr.handler.dataimport.DataImporter.doDeltaImport(DataImporter.java:412) at org.apache.solr.handler.dataimport.DataImporter.runCmd(DataImporter.java:450) at org.apache.solr.handler.dataimport.DataImporter$1.run(DataImporter.java:429) Caused by: java.lang.IllegalArgumentException: deltaQuery has no column to resolve to declared primary key pk='id' at org.apache.solr.handler.dataimport.DocBuilder.findMatchingPkColumn(DocBuilder.java:725) at org.apache.solr.handler.dataimport.DocBuilder.collectDelta(DocBuilder.java:773) at org.apache.solr.handler.dataimport.DocBuilder.doDelta(DocBuilder.java:341) at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:226) ... 3 more Not really relevant to this problem, because I basically want my real time indexing to keep working in spite of this. However, when it's happening, I am pretty sure this is causing my real-time indexing commit to throw this exception: Feb 26, 2013 5:07:51 PM org.apache.solr.common.SolrException log SEVERE: null:org.apache.solr.common.SolrException: Error opening new searcher at org.apache.solr.core.SolrCore.openNewSearcher(SolrCore.java:1310) at org.apache.solr.core.SolrCore.getSearcher(SolrCore.java:1422) at org.apache.solr.core.SolrCore.getSearcher(SolrCore.java:1200) at org.apache.solr.update.DirectUpdateHandler2.commit(DirectUpdateHandler2.java:560) at org.apache.solr.update.processor.RunUpdateProcessor.processCommit(RunUpdateProcessorFactory.java:87) at org.apache.solr.update.processor.UpdateRequestProcessor.processCommit(UpdateRequestProcessor.java:64) at org.apache.solr.update.processor.DistributedUpdateProcessor.processCommit(DistributedUpdateProcessor.java:1007) at org.apache.solr.update.processor.LogUpdateProcessor.processCommit(LogUpdateProcessorFactory.java:157) at org.apache.solr.handler.RequestHandlerUtils.handleCommit(RequestHandlerUtils.java:69) at org.apache.solr.handler.ContentStreamHandlerBase.handleRequestBody(ContentStreamHandlerBase.java:68) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:129) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1699) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:455) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:276) 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:225) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:169) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:168) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:98) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:927) 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:999) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:565) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:309) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:679) Caused by: org.apache.lucene.store.AlreadyClosedException: this IndexWriter is closed at org.apache.lucene.index.IndexWriter.ensureOpen(IndexWriter.java:550) at org.apache.lucene.index.IndexWriter.ensureOpen(IndexWriter.java:563) at org.apache.lucene.index.IndexWriter.nrtIsCurrent(IndexWriter.java:4196) at org.apache.lucene.index.StandardDirectoryReader.doOpenFromWriter(StandardDirectoryReader.java:266) at org.apache.lucene.index.StandardDirectoryReader.doOpenIfChanged(StandardDirectoryReader.java:245) at org.apache.lucene.index.StandardDirectoryReader.doOpenIfChanged(StandardDirectoryReader.java:235) at org.apache.lucene.index.DirectoryReader.openIfChanged(DirectoryReader.java:169) at org.apache.solr.core.SolrCore.openNewSearcher(SolrCore.java:1256) ... 28 more Usually, I can get around this by basically creating a new HttpSolrServer and trying again. But if the problem is very frequent, one more try doesn't work. I don't like the idea of continually trying new solr connections until it works. What's the proper way to fix this? I'm assuming adding a doc with a commitWithMs of "0" is not any different than committing right away, but that suggestion was raised as well. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
