> If an exception occurs in KafkaSystemAdmin.getSystemStreamMetadata (eg
> because the broker returns an error for the partitions metadata request), we
> currently retry in a tight loop. This puts unnecessary load on Kafka, and
> especially risks hammering Zookeeper.
> There should be an exponential back-off in the retry loop.
