             Summary: Order of createNodeList should be respected during collection creation
                 Key: SOLR-6877
                 URL: https://issues.apache.org/jira/browse/SOLR-6877
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.10.2
            Reporter: Steven Bower


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..
