Tha HashMap()... method works fine for storing the metadata, and luke
shows that its there. Of course getting the metadata back for later

I get an empty hashmap back from the above. I also tried using:
Whups, I was wrong, I don't get a HashMap type back, I get
a 'Map' type back (still empty). I don't know if that makes a difference
or not....
That shouldn't make a difference, that interface is wrapped too.
To see what the actual Java class is for that map, you can call getClass()
on it. Maybe I'm missing something obvious here, how do you see that this
Map instance is empty ?
indexCommit = reader.getIndexCommit
indexMetaDataHashMap = indexCommit.getUserData()
with the same result (empty hashmap). Is there a different way to do this?
If you're getting a HashMap back then the PyLucene side of things is
working. If it's empty it could mean that you're doing something wrong
Lucene-wise or that you found a bug there. Could it be that you opened the
IndexReader before the IndexWriter got committed ? If so, reopen() it after
commit or move the opening code. If not, you may want to ask about this on
the Lucene user list at java-u...@lucene.apache.org.
I definitely open the reader after the writer is committed and closed,
they're separate scripts.
Maybe you're not using this API correctly ?
http://lucene.apache.org/java/3_0_3/api/core/org/apache/lucene/index/IndexReader.html#getIndexCommit()
Why aren't you calling reader.getCommitUserData() directly ? (the former is
labeled Expert and liable to change but I don't know either APIs)
http://lucene.apache.org/java/3_0_3/api/core/org/apache/lucene/index/IndexReader.html#getCommitUserData()
Did you ask about this on java-u...@lucene.apache.org ?
Of course, to help with narrowing down the bug, you could write the same
Java code directly and see if you encounter the same problem...
