> Project: Apache Knox
> Issue Type: Bug

> Priority: Major
> Fix For: 3.0.0
>
>
> For services that use Zookeeper based HA there is no documentation about how
> the failover scenario works.
> The failover code is a simple round-robin. All URLs are tried once on
> failover. When the list is exhausted the entire list of URLs is re-fetched
> from Zookeeper and the new list is tried again the same way (if the
> configured number of failover attempts has not been reached).
> Upon failure, the url is marked failed and next is tried and used until it
> fails.
>
> This needs to be explicitly documented for clear understanding of HA workings.
