你需要一个ssh隧道来戳一个洞给emr主机。然后通过jdbc连接。

private static String driverName = "org.apache.hive.jdbc.HiveDriver";
private static String hiveConnectionString = "jdbc:hive2://localhost:8158";
//Need port forwarding
SparkPortForwarding.portForwardForSpark();
Class c = Class.forName(driverName);
Connection connection = DriverManager.getConnection(hiveConnectionString,
                "user", "pwd");
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery(sql);

您可以通过shell进行端口转发，如下所示：

ssh -i ~/mykey.pem -N -L 8158:<maserhost>:10000 hadoop@<masterhost>

或者可以使用jsch库来使用代码

public static void portForwardForSpark() {
    try {
        if(session != null && session.isConnected()) {
            return;
        }
        JSch jsch = new JSch();
        jsch.addIdentity(PATH_TO_SSH_KEY_PEM);
        String host = REMOTE_HOST;
        session = jsch.getSession(USER, host, 22);
        // username and password will be given via UserInfo interface.
        UserInfo ui = new MyUserInfo();
        session.setUserInfo(ui);
        session.connect();
        int assingedPort = session.setPortForwardingL(LPORT, RHOST, RPORT);
        System.out.println("Port forwarding done for the post : " + assingedPort);
    } catch (Exception e) {
        System.out.println(e);
    }
}
