Jethro Bakker updated SOLR-4104:
--------------------------------

    Description:=20
We have got three solr instances and two collections which are replicated t=
wice. So each solr instance has all the data available.=20

The current implementation of CloudSolrServer has 6 slices in my setup but =
the end result is 3 urls which are passed to the load balancer.=20
=20
I think the problem is on the first line of the following code:

{noformat}=20
if (nodes.put(node, nodeProps) =3D=3D null) {
  if (!sendToLeaders || (sendToLeaders && coreNodeProps.isLeader())) {
    String url =3D coreNodeProps.getCoreUrl();
    urlList2.add(url);
  } else if (sendToLeaders) {
    String url =3D coreNodeProps.getCoreUrl();
    replicas.add(url);
  }
}
{noformat}=C2=A0

The precondition of this code is that a node can contain one collection, wh=
ich is not true.
