| <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>SingleProcessHBaseCluster:</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 SingleProcessHBaseCluster |
| or DistributedHBaseCluster provide.</div> |
