I am narrowing down this problem that I have had for a week now... I am using lucene version 2.3.1 and 64 bit java versio 1.5.0-12-b04 running on Linux box. We are merging indexes every 60 seconds and there are 1..* searches occuring at anytime on the indexes. The problem is that we will get an Input /Output error trying to read the index for a search randomly... say every 5th search. I have posted the error before, but have narrowed it down, I believe, to a merge issue.
This is the error that a searcher will output at random times: java.io.IOException: Input/output error java.io.RandomAccessFile.readBytes(Native Method) java.io.RandomAccessFile.read(RandomAccessFile.java:315) at org.apache.lucene.store.FSDirecotry$FSIndexInput.readInternal(FSDirectory.java:550) at org.apache.lucene.store.BufferedIndexInput.readBytes(BufferedInputInput.java:131) at org.apache.lucene.index.CompoundFileReader$CSIndexInput.readInternal(CompoundFileReader.java:240) at org.apache.lucene.instoreBufferedIndexInput.refill(BufferedIndexInput.java: 152) at org.apache.lucene.instoreBufferedIndexInput.readByte(BufferedIndexInput.java: 152) at org.lucene.store.IndexInput.readVInt(IndexInput.java:76) at org.apache.lucene.index.TermBuffer.read(TermBuffer.java:63) at org.apache.lucene.index.SegmentTermEnum.next(SegmentTermEnum.java:123) at org.apache.lucene.index.SegmentTermEnum.scanTo(SegmentTermEnum.java:154) at org.apache.lucene.index.TermInfosReader.scanEnum(TermInfosReader.java:223) at org.apache.lucene.index.TermInfosReader.get(TermInfosReader.java:217) at org.apache.lucene.index.SegmentReader.docFreq(SegmentReader.java:678) at org.apache.lucene.search.IndexSearcher.docFreq(IndexSearcher.java:87) at org.apache.lucene.search.Searcher.docFreqs(searcher.java:118) at org.apache.lucene.search.MultiSearcher.createWeight(MultiSearcher.java:311) at org.apache.lucene.search.Searcher.search(Searcher.java:178) ****************************************************************************** NOW, when I get the above Exception, I check the index using the CheckIndex.check method... As part of the check , this exception is thrown: Error: could not read any segments file in directory java.io.FileNotFoundException: no segments* file found in [EMAIL PROTECTED]/rt10/jetty/20081103 at org.apache.lucene.index.SegmentInfos$findSegmentsFile.run(SegementInfos.java:587) ..... Is there any point in the merging of indexes that the segment files are removed? If I rerun the search, right after this error occurs, the search is ok... I do open a new IndexSearcher... The IndexWriter code is this: IndexWriter combinedWriter = new IndexWriter(currentMergeDir, new StandardAnalyzer()); combinedWriter.addIndexes(dirToMerge); combinedWriter.flush(); combinedWriter.close(); As you can see above, each time there is a merge a new IndexWriter is created, indexes added, flushed and closed. I know you are not supposed to have synchronization issues between writing and flushing , but could there be an issue when you are creating a new searcher at the instant where the files are merged and there are no segments in a dir???
