> queryOnRebalance[0] FAILED java.lang.IllegalStateException: No entry found
> for connection 0. In ClusterConnectionStates.java: node state. 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.
