Hi, When I tried to build an index last night, the following exception occurred during call to IndexWriter.optimze():
java.lang.NullPointerException at org.apache.lucene.index.IndexFileDeleter.findDeletableFiles(IndexFileDeleter.java:88) at org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:1570) at org.apache.lucene.index.IndexWriter.flushRamSegments(IndexWriter.java:1351) at org.apache.lucene.index.IndexWriter.optimize(IndexWriter.java:891) ...... The mergeFactor is set to 500. And the final index file size is about 10Gb. Also since the writer.close() is not called. There's an write.lock file in the index directory. After deleting the write.lock file, I called optimze() again and it complete successfully. Is the indexing successful then? Will any documents be lost due to the above exception? I am using lucene-core-2.1.0 Thanks, Cedric --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
