> When you use the collection api to create a new collection and you specify the "createNodeList"
attribute to the CREATE command it does not preserve the ordering of the node list and thus
does not produce a predictable pattern.
> Use case: I want to create a collection with 12 shards (maxShardsPerNode == 4 and I have
3 servers and I specify createNodeList=server1,server2,server3.. 
> I'd expect to get:
> server1 : shard1,shard4,shard7,shard10
> server2 : shard2,shard5,shard8,shard11
> server3 : shard3,shard6,shard9,shard12
> But what you often get is something not that because the list order isn't respected so
you might get:
> server1 : shard1,shard4,shard7,shard10
> server2 : shard3,shard6,shard9,shard12
> server3 : shard2,shard5,shard8,shard11
> Anyway.. Easy to fix.. patch attached..
