Could you describe what you are trying to accomplish in a bit more detail? Is the cluster being used as a data store or for caching? It would likely help us answer you better.

twemproxy will partition your data, splitting it among multiple Redis instances. If you are trying to fetch the same key from Redis through twemproxy repeatedly it will come from the same node. This article from the Redis documentation is a good explanation of partitioning.
