+<div class="block">This class defines methods that can help with managing HBase clusters
+ from unit tests and system tests. There are 3 types of cluster deployments:
+ <ul>
+ <li><b>MiniHBaseCluster:</b> each server is run in the same JVM in separate threads,
+ used by unit tests</li>
+ <li><b>DistributedHBaseCluster:</b> the cluster is pre-deployed, system and integration tests can
+ interact with the cluster. </li>
+ <li><b>ProcessBasedLocalHBaseCluster:</b> each server is deployed locally but in separate
+ JVMs. </li>
+ </ul>
+ <p>
+ HBaseCluster unifies the way tests interact with the cluster, so that the same test can
+ be run against a mini-cluster during unit test execution, or a distributed cluster having
+ tens/hundreds of nodes during execution of integration tests.
+
+ <p>
+ HBaseCluster exposes client-side public interfaces to tests, so that tests does not assume
+ running in a particular mode. Not all the tests are suitable to be run on an actual cluster,
+ and some tests will still need to mock stuff and introspect internal state. For those use
+ cases from unit tests, or if more control is needed, you can use the subclasses directly.
+ In that sense, this class does not abstract away <strong>every</strong> interface that
+ MiniHBaseCluster or DistributedHBaseCluster provide.</div>
