> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.1.0, 0.10.1.1, 0.10.2.0

>
> When building a topology with tables and StateStores, the StateStores are
> mapped to the source topic names. This map is retrieved via
> {{TopologyBuilder.stateStoreNameToSourceTopics()}} and is used in Interactive
> Queries to find the source topics and partitions when resolving the
> partitions that particular keys will be in.
> There is an issue where by this mapping for a table that is originally
> created with {{builder.table("topic", "table");}}, and then is subsequently
> used in a join, is changed to the join topic. This is because the mapping is
> updated during the call to {{topology.connectProcessorAndStateStores(..)}}.
> In the case that the {{stateStoreNameToSourceTopics}} Map already has a value
> for the state store name it should not update the Map.
