> SolrCloud collection CREATE will put multiple master shards on a single node

>             Project: Solr
>          Issue Type: Bug
>          Components: SolrCloud
>    Affects Versions: 4.1
>            Reporter: Brett Hoerner
>
> This is best described by a photo of my SolrCloud admin: 
> http://i.imgur.com/hW4xnxy.png
> I have a 4 node cluster, with shard count of 2 and replication factor of 2.
> After running something like,
>   
> http://localhost:8983/solr/admin/collections?action=CREATE&name=15724&numShards=2&replicationFactor=2
> The shards seem to be completely randomly placed, which is fine, but some 
> nodes receive more of the share than others (some even receiving none).
> For example, 15724 has given node "backfill-1d" 2 "parts", 
> 15724_shard1_replica2 and 15724_shard2_replica1 but has given "backfill-2d" 
> nothing at all.
> This creates unnecessary load on some nodes, no? Is this something I am 
> supposed to handle myself (I looked, but don't see how).
