Certain elements of my streams app stopped working and I noticed that my logs contain:
[2017-05-23 15:23:09,274] WARN (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator:361) The following subscribed topics are not assigned to any members in the group user-service : [user-service-KSTREAM-KEY-SELECT-0000000038-repartition, user-service-KSTREAM-KEY-SELECT-0000000130-repartition, users, user-service-logins-by-user-repartition] These are precisely the affected topics. Does anyone know what this log is related to, and why this might have happened? I am working on isolating the problem, but if anyone has seen this before, some help/guidance would be much appreciated. Thank you!
