-----------------------------
Resolution: Duplicate
> Randomize the backoff in the clients to avoid all clients from sending
> metadata requests at the same time

> Affects Versions: 0.8.0
> Reporter: Neha Narkhede

> Priority: Critical
> Labels: kafka-0.8, p1
>
> Currently, all producer and consumer clients use a static backoff. So if a
> broker fails, most topics will lose some leaders. All clients will notice the
> absence of a leader at the same time, backoff the same time and send metadata
> requests. Instead, clients should randomize the backoff to avoid a herd effect
