Review request for accumulo.
Bugs: ACCUMULO-2615
https://issues.apache.org/jira/browse/ACCUMULO-2615
Repository: accumulo
Description
-------
What started out as a simplification effort on server configurations ended up
with results that aren't so much simpler but are hopefully more
straightforward. Here is a summary of the more important changes.
* ServerConfiguration is deprecated in favor of the new
ServerConfigurationFactory.
* ServerConfigurationFactory caches configurations not just but namespace or
table ID, but also by instance ID.
* ZooConfigurationFactory takes over the creation logic from ZooConfiguration.
A ZooConfiguration instance is no longer a singleton, but an ordinary instance.
ZooConfigurationFactory caches created ones by instance ID.
* NamespaceConfiguration and TableConfiguration each keep a static map of
ZooCache instances, rather than a single static instance. The map is keyed by
instance ID and namespace/table (resp.) ID.
* getParentConfiguration() was added to all appropriate configurations. (I did
have an interface declaring the method but decided it was not useful.)
* The logic for retrieving properties from ZooCache instances is refactored to
a new ZooCachePropertyAccessor object.
* NamespaceConfWatcher and TableConfWatcher include the configurations they
watch as fields, so they no longer need to repeatedly look them up (formerly in
ServerConfiguration). As a consequence, the watchers no longer attempt to
handle received WatchedEvents for a different namespace or table. (This
*should* never happen - a warning is logged if it does.)

Testing (updated)
-------
Unit tests pass. Basic exercising on a one-node cluster (continuous ingest)
successful. All integration tests pass (after ACCUMULO-2951 and related).
Thanks,
