Yennick Trevels created KAFKA-4953:
--------------------------------------
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
