which leaves the producer in a bad state. in this state, a call to flush(), for
example, will hang indefinitely as the sender thread is not around to flush
batches but theyve not been aborted.
even worse, this can happen in MirrorMaker just before a rebalance, at which
point MM will just block indefinitely during a rebalance (in
beforeReleasingPartitions()).
a rebalance participant hung in such a way will cause rebalance to fail for the
rest of the participants, at which point
ZKRebalancerListener.watcherExecutorThread() dies to an exception (cannot
rebalance after X attempts) but the consumer that ran the thread will remain
live. the end result is a bunch of zombie mirror makers and orphan topic
partitions.
a dead sender thread should result in closing the producer.
a consumer failing to rebalance should shut down.
any issue with the producer or consumer should cause mirror-maker death.

example, will hang indefinitely as the sender thread is not around to flush
batches but theyve not been aborted.
even worse, this can happen in MirrorMaker just before a rebalance, at which

unowned topic partitions.
a dead sender thread should result in closing the producer, and a closed
producer should result in MirrorMaker death.
