The closed by interrupt exception is because the underlying
"leader-finder-thread" has been interrupted - this is done for e.g.,
on a rebalance. Do you see any rebalancing messages in your consumer
logs? How many topics are you consuming? Are the topics present on the
broker and is there a leader for each of them (i.e., without any
leader movement)? Can you try running a console consumer to see if you
see the same behavior?
