Rebalances only involving non-Data nodes are ignored by the SDK

      When performing a rebalance which adds a query node to the cluster, the SDK never begins using that query node. If all query nodes are replaced, queries stop functioning altogether.

      Here is a portion of a log where we added a query node and rebalanced. We ran diagostic pings through the SDK before and after the node was added, they included the same query nodes and the after case did not include the new node.
