Re: from 2.2.0 to 2.3.0

by Michael McCandless-2 :: Rate this Message:

CheckIndex tool is in the 2.3 JAR. Just make sure the JAR is on your
CLASSPATH then run:

java org.apache.lucene.index.CheckIndex <indexDirectory>

However, from that stack trace, this is not a corruption issue in
your existing index. My guess is you would hit this same exception
if you started from a new index because it's being hit when flushing
a new segment (not merging old ones).

How many documents are you adding before closing the writer? Are you
using multiple threads to add documents? What kinds of documents are
you adding?

Can you try disabling asserts, then try to build your index, then run
CheckIndex on the resulting index? It's possible this is an over-
aggressive assert.

I'll go scrutinize that code...
