LIke others before me, I stumbled across this bug, where solr/bin/commit warns that a commit failed when in fact it succeeded quite nicely, while getting collection distribution up & running today:
http://www.mail-archive.com/solr-user@lucene.apache.org/msg04585.html It's a trivial fix, and it seems like it's already been done in trunk: http://svn.apache.org/viewvc/lucene/solr/trunk/src/scripts/commit?r1=543259&r2=555612&view=patch The change has not been applied to 1.2. It might be nice if it were. -Charlie
