Infinispan as Lucene directory provider has "No sub-file with id .fnm found" errors in distributed mode ------------------------------------------------------------------------------------------------------- Key: ISPN-2981 URL: https://issues.jboss.org/browse/ISPN-2981 Project: Infinispan Issue Type: Bug Components: Lucene Directory Affects Versions: 5.2.4.Final Environment: Hibernate Search 4.1.1, Hibernate Core 4.1.4, Lucene 3.5.0, Spring Framework 3.1.1 Reporter: Christopher Wong Assignee: Gustavo Fernandes Fix For: 7.0.0.Beta2, 7.0.0.Final Attachments: infinispan.cfg.xml, luceneindexerrors.txt I have been trying to use Infinispan as a Lucene directory provider under Hibernate Search. A single node writes to the index via JMS. A configuration that uses Infinispan in distributed mode seems to work under development, but under load results in an exception that looks like the following.
