Kafka Streams fails when starting multiple instances
When starting multiple instances of a Kafka Streams application, then instances seem to go into an ERROR state.
To reproduce:
- start an instance of your streams app
- wait till it has started and is working
- start another instance of the same app
Expected behaviour: Rebalance of partitions and continuation of processing
Current behaviour: The first instance fails and goes into an error state. The second instance starts processing.
