Examples of org.apache.hadoop.hbase.LocalHBaseCluster

org.apache.hadoop.hbase.LocalHBaseCluster
This class creates a single process HBase cluster. One thread is created for a master and one per region server. Call {@link #startup()} to start the cluster running and {@link #shutdown()}to close it all down. {@link #join} the cluster is you want to wait onshutdown completion.
Runs master on port 60000 by default. Because we can't just kill the process -- not till HADOOP-1700 gets fixed and even then.... -- we need to be able to find the master with a remote client to run shutdown. To use a port other than 60000, set the hbase.master to a value of 'local:PORT': that is 'local', not 'localhost', and the port number the master should use instead of 60000.
