Hbase Java API示例

我对HBase开发非常陌生。我跟在后面。 我使用的是Hbase-1.1.2版本。当我使用示例代码时，会收到警告。有几种方法被弃用（例如，newhbaseadmin（conf）；）我看到了HBaseAdmin类，它有3个构造函数。在3个构造函数中，有2个被弃用。只有一个构造函数接受“ClusterConnection”作为参数。我不知道我是否遵循了正确的链接来使用HBase。请提供使用最新hbase库的示例。？我正在以独立模式运行HBase。

这应该会有所帮助

    HConnection connection;
    HTableInterface hTableInterface = null;

    Configuration hBaseConfig = HBaseConfiguration.create();
    hBaseConfig.setInt("timeout", 120000);
    //zookeeper quorum, basic info needed to proceed
    hBaseConfig.set("hbase.zookeeper.quorum","host1, host2, host3");
    hBaseConfig.set("hbase.zookeeper.property.clientPort", "2181");
    hBaseConfig.set("zookeeper.znode.parent", "/hbase-unsecure");
    connection = HConnectionManager.createConnection(hBaseConfig);
    hTableInterface = connection.getTable(TableName.valueOf("amarTest"));

    try {   
        Put put = new Put(Bytes.toBytes("999"));
        put.add(Bytes.toBytes("cf"),Bytes.toBytes("name"), Bytes.toBytes("amar"));
        hTableInterface.put(put);
        System.out.println("done");
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        hTableInterface.close();
        connection.close();
    }

以下是我的HBase 2.0示例：

Configuration hBaseConfig = HBaseConfiguration.create();
hBaseConfig.set("hbase.zookeeper.quorum", "192.168.x.xxx");
hBaseConfig.set("hbase.zookeeper.property.clientPort", "2181");
HBaseAdmin.available(hBaseConfig);
Connection connection = ConnectionFactory.createConnection(hBaseConfig);

TableName table1 = TableName.valueOf("test");
Table table = connection.getTable(table1);

CellBuilder cb = CellBuilderFactory.create(CellBuilderType.SHALLOW_COPY);
cb.setRow(Bytes.toBytes("row2"));
cb.setFamily(Bytes.toBytes("cf1"));
cb.setQualifier("qualifier1".getBytes());
cb.setValue(Bytes.toBytes("cell_data2"));
cb.setType(Type.Put);
Cell cell = cb.build();

Put p = new Put(Bytes.toBytes("row2"));
p.add(cell);
table.put(p);

connection.close();

我在Spring Boot 2.0应用程序gradle dependencies中编写了上述演示，如下所示：

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile ('org.apache.hbase:hbase:2.0.0')
    compile ('org.apache.hbase:hbase-client:2.0.0'){
        exclude group :'log4j',module:'log4j'
        exclude group :'org.slf4j',module:'slf4j-log4j12'
        exclude group: 'javax.servlet', module: 'servlet-api'
    }
    compile('org.springframework.boot:spring-boot-configuration-processor')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}
