的Lucene索引适用于Windows，Linux上的

Question

失败，我有码头9.2上运行的Java应用程序。两者都使用相同版本的Jetty。索引器在部署后首次运行应用程序。我在Netbeans的Windows 10开发箱中没有遇到任何问题。当我把它放在一台linux机器上时，它不工作，我只有SSH访问权和有限权限。

Java代码，类人首先运行，类组织运行第二。无论是在同一个Hibernate Session

public static void reindexViaMassIndexer(Class<?> type, SessionFactory factory) { 
    Session session = factory.getCurrentSession(); 
    FullTextSession fullTextSession = Search.getFullTextSession(session); 
    MassIndexerProgressMonitor monitor = new SimpleIndexingProgressMonitor(); 

    try { 
     fullTextSession 
       .createIndexer(type) 
       .typesToIndexInParallel(1) 
       .batchSizeToLoadObjects(BATCH_SIZE) 
       .cacheMode(CacheMode.NORMAL) 
       .threadsToLoadObjects(10) 
       .idFetchSize(BATCH_SIZE) 
       .progressMonitor(monitor) 
       .startAndWait(); 
    } catch (InterruptedException ex) { 
     Logger.getLogger(HibernateLuceneIndexer.class.getName()).log(Level.SEVERE, null, ex); 
    } 

}

人指数成功，组织失败。注意父目录也是jetty：jetty（user：group）。

还需要什么吗？

Answer 1

一个可能的解释是，你是为相同的配置创建多个SessionFactories/EntityManagerFactories，从而实例Hibernate Search的多次和创建的索引文件锁冲突。如果是这样，那么不要。也Hibernate search: persist causes sometimes OverlappingFileLockException

看到另外一个可能的解释：这个版本的Hibernate搜索的是真的老了。您可能遇到自此以后解决的错误。我知道有几个与锁已经解决的错误有关，例如这个：https://stackoverflow.com/a/46284827/6692043
