Re: [Neo4j] Lucene index recovery
It might be that you're not shutting down the server correctly (bin/neo4j stop) or that it's shut down at the same time as there are transactions running. Could you supply your data/graph.db/messages.log to me or look in it to see if there are any lines containing: Close invoked with An example: Close invoked with 3 running transaction(s) 2011/9/1 Peter Neubauer peter.neuba...@neotechnology.com Dima, are you shutting down your database correctly? Make sure you can database.shutdown() and wait for it to finish ...

Re: [Neo4j] Problem with lucene indexing
Classpath? -Original Message- From: user-boun...@lists.neo4j.org [mailto:user-boun...@lists.neo4j.org] On Behalf Of andrew ton Sent: Saturday, October 01, 2011 5:27 AM To: Neo4j_user Subject: [Neo4j] Problem with lucene indexing Hello, I have a problem with indexing when using the Neo4J embedded database. I'm using neo4j-1.5M01, neo4j-lucene-index-1.5M01. I have tried both lucene-core-3.1.0 and lucene-core-3.4.0. Can somebody show me what is wrong here? I create an instance of EmbeddedGraphDatabase as graphDb = new EmbeddedGraphDatabase(mystore); and create index: nodeIndex = graphDb.index().forNodes(nodes, MapUtil.stringMap(provider, lucene, type, fulltext)); When I run unit test I have a problem: com.ericsson.research.semantic.PersistentEmbeddedOntology -Exception caugth while instantiating. No index provider 'lucene' found java.lang.IllegalArgumentException: No index provider 'lucene' found and this is the messages.log in my store Sat Oct 01 01:41:20 PDT 2011: Failed to load index provider lucene LUCENE_31 java.lang.NoSuchFieldError: LUCENE_31 at org.neo4j.index.impl.lucene.LuceneDataSource.clinit(LuceneDataSource.java:88) at org.neo4j.index.impl.lucene.LuceneIndexImplementation.init(LuceneIndexImplementation.java:72) at org.neo4j.index.lucene.LuceneIndexProvider.load(LuceneIndexProvider.java:37) at org.neo4j.kernel.KernelData.loadIndexImplementations(KernelData.java:146) at org.neo4j.kernel.EmbeddedGraphDbImpl$2.initializeIndexProviders(EmbeddedGraphDbImpl.java:180) at org.neo4j.kernel.GraphDbInstance.start(GraphDbInstance.java:159) at org.neo4j.kernel.EmbeddedGraphDbImpl.init(EmbeddedGraphDbImpl.java:190) at org.neo4j.kernel.EmbeddedGraphDatabase.init(EmbeddedGraphDatabase.java:80) at org.neo4j.kernel.EmbeddedGraphDatabase.init(EmbeddedGraphDatabase.java:64) Thank you, ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
