Question

我正在尝试通过JDBC从我的应用程序访问HIVE数据库。我在连接时遇到问题。

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

  /**
 * @param args
 * @throws SQLException
   */
  public static void main(String[] args) throws SQLException {
      try {
      Class.forName(driverName);
    } catch (ClassNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
      System.exit(1);
    }
    System.setProperty("java.security.auth.login.config","gss-jaas.conf");
   //System.setProperty("sun.security.jgss.debug","true");     
   //System.setProperty("javax.security.auth.useSubjectCredsOnly",
   //"false");
    System.setProperty("java.security.krb5.conf","krb5.conf");

    Connection con = DriverManager.getConnection("jdbc:hive2://ip-12-***-156-227.ec2.internal:2999,ip-10-***-123-123.ec2.internal:1299,ip-10-230-137-16.ec2.internal:1299/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2-llap0;principal=123@ABC.COM");
    Statement stmt = con.createStatement();

命令：

  GC1MS94NXH3QKE:hiveserver2-jdbc-kerberos sathishbalu$ mvn clean install
  GC1MS94NXH3QKE:hiveserver2-jdbc-kerberos sathishbalu$ java  -cp $HADOOP_CLASSPATH:target/hiveserver2-jdbc-1.0-jar-with-dependencies.jar  com.test.HiveJDBC

输出：

我在这里想念什么？我花了很多时间尝试进行故障排除，但是没有运气。任何帮助表示赞赏。预先感谢

无法通过JDBC连接到HIVE数据库（使用kerberos）
