New exception (for us) in high-level consumer code -- OK to ignore?
Hello -- we're doing some heavy lifting now with our high-level based
consumer. We open a Consumer Connection per partition within the one JVM,
and are using Kafka 0.72. We saw a burst of the exceptions shown below. Is
this something we should be concerned about? Or is this the normal output
from rebalancing, as the consumer starts up?

Thanks,

Philip
