> "fdx size mismatch" exception in StoredFieldsWriter.closeDocStore() when
> closing index with 500M documents
> ----------------------------------------------------------------------------------------------------------
>
> Key: LUCENE-1521
> URL: https://issues.apache.org/jira/browse/LUCENE-1521
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 2.4
> Reporter: Shon Vella
> Assignee: Michael McCandless
> Priority: Critical
>
> When closing index that contains 500,000,000 randomly generated documents, an
> exception is thrown:
> java.lang.RuntimeException: after flush: fdx size mismatch: 500000000 docs vs
> 4000000004 length in bytes of _0.fdx
> at
> org.apache.lucene.index.StoredFieldsWriter.closeDocStore(StoredFieldsWriter.java:94)

> at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:1562)
> ...
> This appears to be a bug at StoredFieldsWriter.java:93:
> if (4+state.numDocsInStore*8 !=
> state.directory.fileLength(state.docStoreSegmentName + "." +
> IndexFileNames.FIELDS_INDEX_EXTENSION))
> where the multiplication by 8 is causing integer overflow. The fix would be
> to cast state.numDocsInStore to long before multiplying.
> It appears that this is another instance of the mistake that caused bug
> LUCENE-1519. I did a cursory seach for \*8 against the code to see if there
> might be yet more instances of the same mistake, but found none.
