--------------------------------------

             Summary: Global Store: cast exception when initialising with 
in-memory logged state store
                 Key: KAFKA-4953
                 URL: https://issues.apache.org/jira/browse/KAFKA-4953
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 0.10.2.0
            Reporter: Yennick Trevels


Currently it is not possible to initialise a global store with an in-memory 
*logged* store via the TopologyBuilder. This results in the following exception:

{code}
java.lang.ClassCastException: 
org.apache.kafka.streams.processor.internals.GlobalProcessorContextImpl cannot 
be cast to org.apache.kafka.streams.processor.internals.RecordCollector$Supplier

I've created a PR which includes a unit this to verify this behaviour.
