See code HBaseTestingUtility :
public Connection getConnection() throws IOException {
if (this.connection == null) {
this.connection = ConnectionFactory.createConnection(this.conf);
Once you have the connection, you can call:
this.hbaseAdmin = (HBaseAdmin) getConnection().getAdmin();
Code under hbase-server/src/test would be a good place to start searching.
FYI
