Hello all, I am running Solr 6.4.0, and while I am attempting to index my Fedora 4 data, I keep getting warning messages in my solr.log: "WARN (qtp401424608-18) [ x:fedora4] o.a.s.h.a.LukeRequestHandler Error getting file length for [segments_5]". And after that, the indexing stops, and the core is left in a non-current state until I issue a manual commit request to it.
What might be causing this behavior? We did migrate this core from Solr 4 to Solr 6, so I was thinking it might be related to some config setting that works in 4 but messes up in 6? Here is the full stack trace from the log: 2017-02-14 16:51:11.429 WARN (qtp401424608-18) [ x:fedora4] o.a.s.h.a.LukeRequestHandler Error getting file length for [segments_5] java.nio.file.NoSuchFileException: /apps/solr/solr64/cores/fedora4/data/index/segments_5 at sun.nio.fs.UnixException.translateToIOException(UnixException.java:86) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107) at sun.nio.fs.UnixFileAttributeViews$Basic.readAttributes(UnixFileAttributeViews.java:55) at sun.nio.fs.UnixFileSystemProvider.readAttributes(UnixFileSystemProvider.java:144) at sun.nio.fs.LinuxFileSystemProvider.readAttributes(LinuxFileSystemProvider.java:99) at java.nio.file.Files.readAttributes(Files.java:1737) at java.nio.file.Files.size(Files.java:2332) at org.apache.lucene.store.FSDirectory.fileLength(FSDirectory.java:243) at org.apache.lucene.store.NRTCachingDirectory.fileLength(NRTCachingDirectory.java:128) at org.apache.lucene.store.FilterDirectory.fileLength(FilterDirectory.java:67) at org.apache.solr.handler.admin.LukeRequestHandler.getFileLength(LukeRequestHandler.java:614) at org.apache.solr.handler.admin.LukeRequestHandler.getIndexInfo(LukeRequestHandler.java:587) at org.apache.solr.handler.admin.LukeRequestHandler.handleRequestBody(LukeRequestHandler.java:138) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:166) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2306) at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:658) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:464) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:345) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:296) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1691) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:582) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:548) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:226) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1180) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:512) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1112) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:213) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:119) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134) at org.eclipse.jetty.server.Server.handle(Server.java:534) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:320) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:251) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:273) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:95) at org.eclipse.jetty.io.SelectChannelEndPoint$2.run(SelectChannelEndPoint.java:93) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.executeProduceConsume(ExecuteProduceConsume.java:303) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.produceConsume(ExecuteProduceConsume.java:148) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.run(ExecuteProduceConsume.java:136) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:671) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:589) at java.lang.Thread.run(Thread.java:745) Thanks, -Peter -- Peter Eichman Senior Software Developer University of Maryland Libraries peich...@umd.edu
