    Hi
    I have java code:
    import org.apache.hadoop.conf.Configuration;
    import org.apache.hadoop.hbase.HBaseConfiguration;
    import org.apache.hadoop.hbase.HColumnDescriptor;
    import org.apache.hadoop.hbase.HTableDescriptor;
    import org.apache.hadoop.hbase.client.HBaseAdmin;
    import org.apache.hadoop.hbase.util.Bytes;
    public class Hbase_connect {
    public static void main(String[] args) throws Exception {
    Configuration conf = HBaseConfiguration.create();
    conf.set(“hbase.zookeeper.quorum”, “sandbox.hortonworks.com”);
    conf.set(“hbase.zookeeper.property.clientPort”, “2181”);
    conf.set(“hbase.rootdir”, “hdfs://sandbox.hortonworks.com:8020/apps/hbase/data”);
    conf.set(“zookeeper.znode.parent”, “/hbase-unsecure”);
    HBaseAdmin admin = new HBaseAdmin(conf);
    HTableDescriptor[] tabdesc = admin.listTables();
    for(int i=0; i<tabdesc.length; i++) {
    System.out.println(“Table = ” + new String(tabdesc [i].getName()));
    }
    }
    }

    [hbase@sandbox hbase_connect]$ java -cp ./:./libs/*:./libs/hbase-0.96.2-hadoop2/lib/* Hbase_connect gives me:
