Subject Re: Empty Solr 4.2.1 can not create Collection
Date Mon, 08 Apr 2013 18:06:42 GMT
The scenario above needs to have collection1 removed from the solr.xml to
work. This, I believe, is the "Empty Solr" scenario that you are talking
about. If you don't remove collection1 from solr.xml on all the solr
instances, they will get tripped up on collection1 during these steps.

If you startup with collection1 in solr.xml it's best to startup the
initial Solr instance with the bootstrap-conf parameter so Solr can
properly create this collection.
