Stuart commented on KAFKA-6659:
-------------------------------
Hi I would like to pick this Jira up. I have found the code section
ProcessorContextImpl, wanted some advice on the type of message wanted. Do we
want to enhance the message to include "... has no access to StateStore
questions-awaiting-answers-store 'as the store is not connected to the
processor'?
Any help on the hint message to fix the issue would be great?
