If there's a stability issue with the zookeeper client, then that
should be addressed.

ZK is a fine tool for service discovery and coordination.  It seems
like any new system that forced me, as a consumer, to use yet another
system to bootstrap and discover where my brokers are for a topic
would be a step backward.

I'm curious, why, specifically, is removing ZK a design goal
(especially when it's such a core component of the broker)?  I think
of other projects, like HBase, which seem to have no issue with using
ZK in their client.
