<div class="block">Facility for testing HBase. Replacement for
old HBaseTestCase and HBaseClusterTestCase functionality.
Create an instance and keep it around testing HBase. This class is
meant to be your one-stop shop for anything you might need testing. Manages
one cluster at a time only. Managed cluster can be an in-process
<a href="../../../../org/apache/hadoop/hbase/MiniHBaseCluster.html" title="class in org.apache.hadoop.hbase"><code>MiniHBaseCluster</code></a>, or a deployed cluster of type <code>DistributedHBaseCluster</code>.
Not all methods work with the real cluster.
Depends on log4j being on classpath and
hbase-site.xml for logging and test-run configuration. It does not set
logging levels.
In the configuration properties, default values for master-info-port and
region-server-port are overridden such that a random port will be assigned (thus
avoiding port contention if another local HBase instance is already running).
<p>To preserve test data directories, pass the system property "hbase.testing.preserve.testdir"
setting it to true.</div>

TODO: There should be a more coherent way of doing this. Unfortunately the way tests are
written, not all start() stop() calls go through this class. Most tests directly operate on
the underlying mini/local hbase cluster. That makes it difficult for this wrapper class to
maintain the connection state automatically. Cleaning this is a much bigger refactor.</div>
