FAILED  java.lang.IllegalStateException: No entry found for connection 0. In ClusterConnectionStates.java:
node state.
> {noformat}
> This happens locally. Happened to KStreamAggregationIntegrationTest.java.shouldReduce()
once too. 
> Not clear this is streams related. Also, it's hard to reproduce since it doesn't happen
all the time.
