> Currently, the consumer client caches the host/port of a broker and never
> refreshes the cache. This means that if a broker changes to a different host,
> the consumer client won't be able to connect to the new host without a
> restart. One possibility is to change AbstractFetcherManager to maintain a
> map of <Broker, fetcher>, instead of <broker id, fetcher>.
