Question

我是Sandbox HDP的新手，我尝试使用JDBC连接到Hive，我使用了Ambari提供的JDBC URL，这是我的代码：

private static String driverName = "org.apache.hadoop.hive.jdbc.HiveDriver";  

    public static void main(String[] args) throws SQLException {
        try {
            Class.forName(driverName);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
        }
        Connection con = DriverManager.getConnection(
            "jdbc:hive2://sandbox-hdp.hortonworks.com:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2");
}

但是，我遇到了这个错误：

Exception in thread "main" java.sql.SQLException: Invalid URL: jdbc:hive2://sandbox-hdp.hortonworks.com:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2
    at org.apache.hadoop.hive.jdbc.HiveConnection.<init>(HiveConnection.java:86)
    at org.apache.hadoop.hive.jdbc.HiveDriver.connect(HiveDriver.java:106)
    at java.sql.DriverManager.getConnection(Unknown Source)
    at java.sql.DriverManager.getConnection(Unknown Source)
    at Hive2.main(Hive2.java:21)

如果有人可以帮助解决此问题，将不胜感激
