Subject Re: Empty Solr 4.2.1 can not create Collection
Date Tue, 09 Apr 2013 08:21:55 GMT
Hi,
thanks for your faster answer.

You don't use the Collection API - may I ask you why ?
Therefore you have to setup everything (replicas, ...) manually..., 
which I would like to avoid.

Also what I don't understand, why my steps work in 4.0 but won't in 4.2.1...
Any clues ?

Kind Regards
Alexander
