Matthias J. Sax created KAFKA-6659:
--------------------------------------

             Summary: Improve error message if state store is not found
                 Key: KAFKA-6659
                 URL: https://issues.apache.org/jira/browse/KAFKA-6659
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Matthias J. Sax


If a processor tries to access a store but the store is not connected to the processor, Streams fails with
{quote}Caused by: org.apache.kafka.streams.errors.TopologyBuilderException: Invalid topology building: Processor KSTREAM-TRANSFORM-0000000036 has no access to StateStore questions-awaiting-answers-store
{quote}
We should improve this error message and give a hint to the user how to fix the issues.
