IndeIndexWriter.optimize() throws FileNotFoundException and IOException
-----------------------------------------------------------------------
Key: LUCENE-3422
URL: https://issues.apache.org/jira/browse/LUCENE-3422
Project: Lucene - Java
Issue Type: Bug
Reporter: Elizabeth Nisha
I am using lucene 3.0.2 search APIs for my application.
Indexed data is about 350MB and time taken for indexing is 25 hrs. Search
indexing and Optimization runs in two different threads. Optimization runs for
every 1 hour and it doesn't run while indexing is going on and vice versa. When
optimization is going on using IndexWriter.optimize(), FileNotFoundException
and IOException are seen in my log and the index file is getting corrupted, log
says
1. java.io.IOException: No sub-file with id _5r8.fdt found
[The file name in this message changes over time (_5r8.fdt, _6fa.fdt, _6uh.fdt,
..., _emv.fdt) ]
2. java.io.FileNotFoundException: /local/groups/necim/index_5.3/index/_bdx.cfs
(No such file or directory)
3. java.io.FileNotFoundException: /local/groups/necim/index_5.3/index/_hkq.cfs
(No such file or directory)
