java: 写入数据到HBase

一、添加依赖

        <dependency><groupId>org.apache.hadoop</groupId><artifactId>hadoop-client</artifactId><version>2.6.0</version></dependency><dependency><groupId>org.apache.hbase</groupId><artifactId>hbase-client</artifactId><version>2.4.2</version></dependency>

二、调用API写HBase示例

package cn.edu.tju;import org.apache.commons.io.IOUtils;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.TableName;
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 TestHbaseWrite {public static void main(String[] args) throws Exception{Configuration config = HBaseConfiguration.create();// create configuration//zookeeper 地址config.set("hbase.zookeeper.quorum","xxx.xxx.xxx.xxx");////zookeeper端口config.set("hbase.zookeeper.property.clientPort", "2181");////表名，必须提前在hbase中创建String tableName ="c1";//row keyString rowKey = "myRowKeyTest";//family，必须是hbase中有的familyString familyName = "fam3";//columnString columnName = "age";//valueString columnValue = "18";Connection connection = ConnectionFactory.createConnection(config);Table table = null;try {table = connection.getTable(TableName.valueOf(tableName));Put put = new Put(Bytes.toBytes(rowKey));put.addColumn(familyName.getBytes(), Bytes.toBytes(columnName),Bytes.toBytes(columnValue));table.put(put);}catch(Exception ex) {System.out.println(ex.getMessage());}finally {IOUtils.closeQuietly(table);}}
}
