Solr 4.2 implements a feature to proxy requests if the core not exists in node 
requested. https://issues.apache.org/jira/browse/SOLR-4210

Actually exists a bug in this mechanism 
https://issues.apache.org/jira/browse/SOLR-4584 

Without the proxy feature, creating the cores using manually or on automatic 
way, you only can query the collection in nodes that have least 1 replica of 
the collection.

If you have a solrCluster with 4 nodes and the collection only have 2 shards 
without replicas, then you can only query the collection in 50% of the cluster. 
(assuming that proxy request mechanism doesn't work properly)

When I said to create manually the collection, you need to create manually all 
shards that form the collection and the replicas in the others nodes of the 
cluster. It takes work, but if you want have some control you need to pay the 
price.

If it is possible that you can manage the name of shard with the collection 
API, the documentation doesn't say how.
