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

             Summary: Cannot access GlobalKTable store from KStream.transform()
                 Key: KAFKA-6894
                 URL: https://issues.apache.org/jira/browse/KAFKA-6894
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 1.1.0
            Reporter: Robert Yokota
            Assignee: Robert Yokota


I was trying to access a store from a {{GlobalKTable}} in 
{{KStream.transform()}}, but I got the following error:

{code}
org.apache.kafka.streams.errors.TopologyException: Invalid topology: StateStore 
globalStore is not added yet.

        at 
org.apache.kafka.streams.kstream.internals.KStreamImpl.transform(KStreamImpl.java:521)
{code}

I was able to make a change to 
{{InternalTopologyBuilder.connectProcessorAndState}} to allow me to access the 
global store from {{KStream.transform()}}.  I will submit a PR for review.
