Question

我正在尝试通过JDBC连接到Hive-Server2。服务器启用了kerberos。

我正在使用以下代码，我正在运行存在keytab文件的边缘节点的代码

我错过了什么？

import org.apache.hadoop.security.UserGroupInformation;

public class HiveJdbcClient {
private static String driverName = "org.apache.hive.jdbc.HiveDriver";

public static void main(String[] args)
        throws SQLException, IOException, ClassNotFoundException {

    org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
    conf.set("hadoop.security.authentication", "Kerberos");
    UserGroupInformation.setConfiguration(conf);

    int ch = 1;
    String USER = (ch == 0) ? "hive/_HOST@HADOOP_DEV9.xyz.COM"
            : "abcd@HADOOP_DEV9.xyz.COM";
    String PASSWORD = (ch == 0) ? "/etc/security/keytabs/hive.service.keytab"
            : "/u/users/abcd/.abcd.keytab";
    System.out.println("User = " + USER + "Keytab =" + PASSWORD);

    File f = new File(PASSWORD);
    if (f.exists()) {
        System.out.println("File exists");
    } else {
        System.out.println("File not exists");
    }
    UserGroupInformation.loginUserFromKeytab(USER, PASSWORD);

    String ConnectionURL = "jdbc:hive2://tstr400382.xyz.com:2181,tstr400383.xyz.com:2181,tstr400384.xyz.com:2181,tstr400386.xyz.com:2181,tstr400387.xyz.com:2181/;"
            + "serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2"
            + ";principal=hive/_HOST@HADOOP_DEV9.xyz.COM;transportMode=http;httpPath=cliservice";

    System.out.println("below connection url");

    Class.forName(driverName);
    Connection con = DriverManager.getConnection(ConnectionURL);
    Statement stmt = con.createStatement();
    String sql = "show databases;";
    System.out.println("Running: " + sql);
    ResultSet res = stmt.executeQuery(sql);
    if (res.next()) {
        System.out.println(res.getString(1));
    }

}
}

我收到以下错误

我能够做到

kinit -kt /u/users/abcd/.abcd.keytab abcd@HADOOP_DEV9.xyz.COM

密钥表上的Klist

Keytab name: FILE:.abcd.keytab
   KVNO Principal
---- --------------------------------------------------------------------------
   1 abcd@HADOOP_DEV9.xyz.COM
   1 abcd@HADOOP_DEV9.xyz.COM

我很长时间坚持下去，请帮忙。

我使用this进行学习，然后我跟着它

Answer 1

用于服务主体＆＃34; hive＆＃34;的Kerberos领域名称可能存在差异。和用户主体＆＃34; abcd＆＃34;如下所述：

hive/_HOST@<KDC_REALM_1>

abcd@<KDC_REALM_2>

请与群集管理员确认，如果存在差异，请进行必要的更改。
