Here is part of code
private String hbaseZookeeperQuorum = "master1.medcloud.com";
HTablePool tablepool;
public void createTable() throws IOException
{
//Create Configuration
conf = HBaseConfiguration.create();

//If Eclipse on a diff machine
conf.set("hbase.zookeeper.quorum", hbaseZookeeperQuorum);
conf.set("hbase.zookeeper.property.clientPort", "2181");
tablepool = new HTablePool(conf, Integer.MAX_VALUE);

//Instantiate an HbaseAdmin Instance
admin = new HBaseAdmin(conf);
//Instantiate a HTableDescriptor
HTableDescriptor patient = new HTableDescriptor(TABLE_NAME);
//Instantiate a HColumnDescriptor
HColumnDescriptor coldef = new HColumnDescriptor(CF);
//Add Family
patient.addFamily(coldef);
//Create Table
admin.createTable(patient);
//Check if available
boolean avail = admin.isTableAvailable(TABLE_NAME);
System.out.println("Table available: " + avail);
