Mike,
Verified that I have the latest source code.
Here are the alg files and the checkindexer output.

(Please note that ThreadedIndexWriter is source code available with
the upcoming revision to Lucene in Action.)
Phil, is it possible you are using an older version of the book's
source code? In particular, can you check whether your version of
ThreadedIndexWriter.java has this:
public void close(boolean doWait) throws CorruptIndexException,
IOException {
finish();
super.close(doWait);
}
(I vaguely remember that being missing from earlier releases, which
could explain what you're seeing). If you are missing that, can you
download the current code from http://www.manning.com/hatcher3 and try
again?
If that's not the problem... can you post the benchmark alg you are
using in each case?

Hi Phil,
It's 5 threads for IndexWriter.
For ThreadedIndexWriter, I used:
writer.num.threads=16
writer.max.thread.queue.size=80
Thanks,

Hi Jibo,
Your mergeFactor is different, and the resulting numFiles (segment
files) is different. Maybe each thread is responsible for a segment
file. Just curious - do you have 3 threads?
Phil
