             Summary: Kafka Streams gets stuck if metadata is missing
                 Key: KAFKA-4476
             Project: Kafka
          Issue Type: Bug
          Components: streams
            Reporter: Matthias J. Sax
            Assignee: Matthias J. Sax
            Priority: Critical

When a Kafka Streams application gets started for the first time, it can happen 
that some topic metadata is missing when {{StreamPartitionAssigner#assign()}} 
is called on the group leader instance. This can result in an infinite loop 
within {{StreamPartitionAssigner#assign()}}. This issue was detected by 
{{ResetIntegrationTest}} that does have a transient timeout failure (c.f. -- this issue was re-opened 
multiple times as the problem was expected to be in the test -- however, that 
is not the case).
