Question

我想知道是否以及如何连接到我使用的HBaseTestTable （org.apache.hadoop.hbase.HBaseTestingUtility;）通过Phoenix。我希望成功连接到Hbase，然后插入Test表并从Test表中检索数据。我已经能够创建一个HbaseTable。但无法通过凤凰城连接到它。也无法使用writeToPhoenix函数。

我正在分享我写的代码：

@BeforeClass
public static void init() throws Exception {

    testingUtility = new HBaseTestingUtility();
    testingUtility.startMiniCluster();
    hbaseConfiguration = testingUtility.getHBaseCluster().getConfiguration();

    String zkQuorum = "localhost:" + testingUtility.getZkCluster().getClientPort();
    Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
    java.sql.Connection connection = DriverManager.getConnection("jdbc:phoenix:"+zkQuorum);
    connection.setAutoCommit(true);

    try {
        Statement statement = connection.createStatement();
        statement.executeUpdate("CREATE TABLE TEST(" +
                                "KEY VARCHAR NOT NULL," +
                                "VALUE1 VARCHAR NOT NULL," +
                                "VALUE2 VARCHAR NOT NULL," +
                                "CONSTRAINT PK PRIMARY KEY(KEY)" +
                                ")");
        connection.commit();
        log.info("HBase table via Phoenix created successfully.");

    } catch (Exception e) {
        e.printStackTrace();
    }

}
