----------------------------------
Summary: disableLogging() causes an initialization loop
Key: KAFKA-5989
URL: https://issues.apache.org/jira/browse/KAFKA-5989
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 0.11.0.1
Reporter: Tuan Nguyen
Attachments: App.java
Using {{disableLogging()}} for either of the built-in state store types causes
an initialization loop in the StreamThread.
Case A - this works just fine:
{code}
final StateStoreSupplier testStore = Stores.create(topic)
.withStringKeys()
.withStringValues()
.inMemory()
// .disableLogging()
.maxEntries(10)
.build();
{code}
Case B - this does not:
{code}
final StateStoreSupplier testStore = Stores.create(topic)
.withStringKeys()
.withStringValues()
.inMemory()
.disableLogging()
.maxEntries(10)
.build();
{code}
A brief debugging dive shows that in Case B,
{{AssignedTasks.allTasksRunning()}} never returns true, because of a remnant
entry in {{AssignedTasks#restoring}} that never gets properly restored.
See [^App.java] for a working test (requires ZK + Kafka ensemble, and at least
one keyed message produced to the "test" topic)
