Joel Koshy commented on KAFKA-890:
----------------------------------

+1

It is worth noting that this is useful even in the presence of a VIP since the consumers don't currently use a VIP to to look up metadata.

> The list of brokers in the metadata request is never shuffled. Which means that if some clients are not using a VIP for metadata requests, the first broker ends up servicing most metadata requests, leaving imbalanced load on the brokers. This issue is even more pronounced when there are several thousand clients talking to a cluster each using a broker list to fetch metadata.
