Error deleting a document when using the compound file index
Hi,
I am just testing Lucene 1.3 RC with the Compound index option on. When I
come to delete an existing document in the index to re-update a document, I
get an unable to obtain lock error.
java.io.IOException: Lock obtain timed out
at org.apache.lucene.store.Lock.obtain(Lock.java:97)
at org.apache.lucene.index.IndexReader.delete(IndexReader.java:279)
at org.apache.lucene.index.IndexReader.delete(IndexReader.java:312)
at objects.CH_Lucene.updateDocument(CH_Lucene.java:1065)
at
servlets.CH_SearchConnection.updateDocument(CH_SearchConnection.java:1048)
at
functions.CH_UpdateThread.updateDocument(CH_UpdateThread.java:255)
at functions.CH_UpdateThread.run(CH_UpdateThread.java:132)
I am using the following snippet of code to remove the previous document
entry.
DecimalFormat df = new DecimalFormat("########");
df.setMinimumIntegerDigits(8);
Term docNumberTerm = new Term("Field10", df.format(ldoc));
IndexReader reader = IndexReader.open(location);
// Delete old term if present
if (reader.docFreq(docNumberTerm) > 0)
{
reader.delete(docNumberTerm);
}
reader.close();
I did not get this when I was using the normal index file structure. Is
there a way round this?
Regards,
Paul

Paul,
I just started using 1.3 final (labeled 1.4 RC1) and ran into a similar
problem (though I'm not using the compound file option). My code ran just
fine all the way through 1.3RC3, but with the latest release, the
reader.delete() threw a "Lock obtain timed out" IOException. What I finally
did was locate the place earlier in my code where the FSDirectory was first
created, and immediately followed it with a call to
IndexReader.unlock(fsdir). So far, that appears to have done the trick (but
I haven't had much time to fully test it yet).
Regards,
Terry
