> "fdx size mismatch" overflow causes RuntimeException
> ----------------------------------------------------
>
> Key: LUCENE-2420
> URL: https://issues.apache.org/jira/browse/LUCENE-2420
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/index
> Affects Versions: 3.0.1
> Environment: CentOS 5.4
> Reporter: Steven Bethard
>
> I just saw the following error:
> java.lang.RuntimeException: after flush: fdx size mismatch: -512764976 docs
> vs 30257618564 length in bytes of _0.fdx file exists?=true
> at
> org.apache.lucene.index.StoredFieldsWriter.closeDocStore(StoredFieldsWriter.java:97)
> at
> org.apache.lucene.index.DocFieldProcessor.closeDocStore(DocFieldProcessor.java:51)
> at

> org.apache.lucene.index.IndexWriter.closeInternal(IndexWriter.java:1658)
> at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:1621)
> at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:1585)
> Note the negative SegmentWriteState.numDocsInStore. I assume this is because
> Lucene has a limit of 2 ^ 31 - 1 = 2147483647 (sizeof(int)) documents per
> index, though I couldn't find this documented clearly anywhere. It would have
> been nice to get this error earlier, back when I exceeded the limit, rather
> than now, after a bunch of indexing that was apparently doomed to fail.
> Hence, two suggestions:
> * State clearly somewhere that the maximum number of documents in a Lucene
> index is sizeof(int).
> * Throw an exception when an IndexWriter first exceeds this number rather
> than only on close.
