Christopher Tubbs commented on ACCUMULO-4050:
---------------------------------------------
After some thought, I don't think we actually need a hierarchy of config
containers (though, it might help to visualize it that way). We just need code
that knows how to create the hierarchy in the snapshots, when the snapshot is
requested. This can be done based on the type The snapshot can be provided
directly from the ServerConfigurationFactory.
So, what we need is:
* The ServerConfigurationFactory is a big bag of configuration containers, each
corresponding to a single ZK path.
* The getSnapshot methods on the factory know how to construct a hierarchy of
snapshots from the relevant containers' current contents.
> Serialize table configs into a single ZK node

> Use a single ZK node to store table configs, rather than split across
> multiple configs. This should make it easier to implement atomic changes to
> the configuration, and should simplify reading loading/saving configuration
> from/to ZooKeeper.
