HBASE-1.2.4开发环境搭建

在《HA Hadoop-2.7.3+Hbase-1.2.4搭建》的基础上，整理记录如何在eclipse上进行进行hbase java api的应用。

hadoop以及hbase都是搭建在ubuntu虚拟机里，而eclipse则是在windows上。

1、配置windowns的host文件，添加虚拟机中相应的域名。

192.168.42.132 chan-takchi-03192.168.42.131 chan-takchi-02192.168.42.130 chan-takchi-01192.168.42.129 chan-takchi

2、把hbase-1.2.4/lib里的jar文件添加到项目classpath。

3、编写java代码。

package chan.takchi.hbase;import java.io.IOException;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.TableName;import org.apache.hadoop.hbase.client.Admin;import org.apache.hadoop.hbase.client.Connection;import org.apache.hadoop.hbase.client.ConnectionFactory;import org.apache.hadoop.hbase.client.Put;import org.apache.hadoop.hbase.client.Table;import org.apache.hadoop.hbase.util.Bytes;public class HbaseDemo {        public static void Test(String[] args) throws Exception {    // Instantiating configuration classConfiguration conf = HBaseConfiguration.create();conf.set("hbase.zookeeper.quorum", "192.168.42.132,192.168.42.131,192.168.42.130");;Connection conn = ConnectionFactory.createConnection(conf);Admin admin = conn.getAdmin();// Instantiating table descriptor classHTableDescriptor tableDescriptor = new HTableDescriptor(TableName.valueOf("emp"));// Adding column families to table descriptortableDescriptor.addFamily(new HColumnDescriptor("personal"));tableDescriptor.addFamily(new HColumnDescriptor("professional"));// Execute the table through adminSystem.out.println("Creating the table ");admin.createTable(tableDescriptor);System.out.println("Table created ");    }        public static void addColumn(String[] args) throws IOException    {    // Instantiating configuration classConfiguration conf = HBaseConfiguration.create();conf.set("hbase.zookeeper.quorum", "192.168.42.132,192.168.42.131,192.168.42.130");;Connection conn = ConnectionFactory.createConnection(conf);Table t = conn.getTable(TableName.valueOf("students"));Put put = new Put(Bytes.toBytes("1234"));//rowkey        put.addColumn(Bytes.toBytes("info"), Bytes.toBytes("address"), Bytes.toBytes("SZ"));        t.put(put);        System.out.println("add data Success!");    }}

4、运行成功后，用shell命令查看创建的表吧。
