HBase JAVA API怎么用

這篇文章主要介紹HBase JAVA API怎么用，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！

Maven

pom.xml

     <dependencies>        <dependency>            <groupId>org.apache.hbase</groupId>            <artifactId>hbase-client</artifactId>            <version>1.3.5</version>        </dependency>        <dependency>            <groupId>org.apache.hbase</groupId>            <artifactId>hbase-server</artifactId>            <version>1.3.5</version>        </dependency>    </dependencies>

靜態代碼塊

private static Connection connection = null;    private static Admin admin = null;;    static {        try {            Configuration configuration = HBaseConfiguration.create();            configuration.set("hbase.zookeeper.quorum", "aliyun:2181");            connection = ConnectionFactory.createConnection(configuration);            admin = connection.getAdmin();        } catch (IOException e) {            e.printStackTrace();        }    }

創建表

    //創建表    public static void createTable(String tableName, String[] cols) throws IOException {        TableName table = TableName.valueOf(tableName);        if (admin.tableExists(table)) {            System.out.println("表已存在！");        } else {            HTableDescriptor hTableDescriptor = new HTableDescriptor(tableName);            for (String col : cols) {                HColumnDescriptor hColumnDescriptor = new HColumnDescriptor(col);                hTableDescriptor.addFamily(hColumnDescriptor);            }            try {                admin.createTable(hTableDescriptor);            } catch (IOException e) {                e.printStackTrace();            }        }    }
