[ http://issues.apache.org/jira/browse/LUCENE-555?page=comments#action_12376095 ]
Doug Cutting commented on LUCENE-555: ------------------------------------- Dan, Lucene has never had a recovery mechanism other than rebuilding the index. This is usually practical, since Lucene is not meant to be used as a primary repository for data, but rather as an index, to help folks find things they already have. So perhaps we should recategorize this as a feature request, rather than a bug, no? Please note that it might be difficult to add, since Lucene, in order to keep indexes relatively small, keeps no journal of transactions. Finally, Lucene is not a database. It is a full-text indexing system. The requirements are different. > Index Corruption > ---------------- > > Key: LUCENE-555 > URL: http://issues.apache.org/jira/browse/LUCENE-555 > Project: Lucene - Java > Type: Bug > Components: Index > Versions: 1.9 > Environment: Linux FC4, Java 1.4.9 > Reporter: dan > Priority: Critical > > Index Corruption > >>>>>>>>> output > java.io.FileNotFoundException: ../_aki.fnm (No such file or directory) > at java.io.RandomAccessFile.open(Native Method) > at java.io.RandomAccessFile.<init>(RandomAccessFile.java:204) > at > org.apache.lucene.store.FSIndexInput$Descriptor.<init>(FSDirectory.java:425) > at org.apache.lucene.store.FSIndexInput.<init>(FSDirectory.java:434) > at org.apache.lucene.store.FSDirectory.openInput(FSDirectory.java:324) > at org.apache.lucene.index.FieldInfos.<init>(FieldInfos.java:56) > at > org.apache.lucene.index.SegmentReader.initialize(SegmentReader.java:144) > at org.apache.lucene.index.SegmentReader.get(SegmentReader.java:129) > at org.apache.lucene.index.SegmentReader.get(SegmentReader.java:110) > at > org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:674) > at > org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:658) > at org.apache.lucene.index.IndexWriter.optimize(IndexWriter.java:517) > >>>>>>>>> input > - I open an index, I read, I write, I optimize, and eventually the above > happens.
