zookeeper loading

Hi,

When the zk.connect property of the Kafka server is specified with a comma
separated host:port list, such as "127.0.0.1:3000,127.0.0.1:3001,
127.0.0.1:3002"., does that mean that every ZK connection attempt goes to
the first listed server if it exists? And does that represent a risk of
driving too much traffic to one ZK node if the same zk.connect list is used
everywhere in  a multi-broker system?

Regards
Dennis

No. The zookeeper client shuffles the list so that the load is distributed
across all zk servers in the connection url.

Thanks,
Neha
