---------------------------------------
Fix Version/s: 2.4.1

> --------------------------------------------------------------------------

> Key: LUCENE-1430
> URL: https://issues.apache.org/jira/browse/LUCENE-1430

> Affects Versions: 2.1, 2.2, 2.3, 2.3.1, 2.3.2, 2.4
> Reporter: Michael McCandless
> Assignee: Michael McCandless

> Spinoff from here:
> http://www.nabble.com/Runtime-exception-when-creating-IndexSearcher-to20226279.html
> If you open an IndexSearcher/Reader, passing in String or File, then
> closeDirectory is set to true in the reader.
> If the index has a single segment, then SegmentReader.get is used to
> open the index. If an IOException is hit in there, the SegmentReader
> closes itself and then closes the directory since closeDirectory is
> true.
> The problem is, the retry logic in SegmentInfos (to look for another
> segments_N to try) kicks in and hits an AlreadyClosedException,
> masking the original root cause.
> Workaround is to separately get the Directory using
> FSDirectory.getDirectory, and then instantiate IndexSearcher/Reader
> from that.
> This manifests as masking the root cause of a corrupted single-segment
> index with a confusing AlreadyClosedException. You could also hit
> the false exception if the writer was in the process of committing
> (ie, a retry was really needed) or if there is some transient IO
> problem opening the index (eg too many open files).
