config.set("hbase.zookeeper.quorum", "zookeepernode0,zookeepernode1,zookeepernode2");
config.set("hbase.zookeeper.property.clientPort", "2181");
config.set("hbase.cluster.distributed", "true");

HBaseAdmin admin = new HBaseAdmin(config);
TableName[] tm = admin.listTableNames();
for(int i = 0; i<tm.length;i++){
System.out.println(tm[i].getNameAsString());
