Question

我正在尝试通过JDBC从我的应用程序访问HIVE数据库。我面临一些连接问题。我在这里尝试了很多事情，例如尝试TCP等，但还是失败了。

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("sun.security.jgss.debug","true");
        System.setProperty("java.security.krb5.realm","FDLDEV.COM");
        System.setProperty("java.security.auth.useSubjectCredsOnly","false");
        System.setProperty("java.security.krb5.conf","krb5.conf");
        System.setProperty("java.security.krb5.kdc","10.230.137.236");
        System.setProperty("sun.security.krb5.debug", "true");

          try{
              LOG.info("Starting:");
              org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
              conf.set("hadoop.security.authentication", "kerberos");
              UserGroupInformation.setConfiguration(conf);
              UserGroupInformation.loginUserFromKeytab("122*121@ABC.COM", "122*121.keytab");
    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();

Krb5.conf：

[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = ABC.COM
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = true

[realms]    
FDLDEV.COM = {
   kdc = 10.***.***.236
   admin_server = 10.***.***.236
}

[domain_realm]
.abc.com = ABC.COM
 abc.com = ABC.COM

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

Answer 1

我遇到了同样的问题...这是因为代码没有加载所有的conf文件。因此，其中一些人尝试与kerberos连接，但是kerberos拒绝了它，因此您无法获得ICMP端口。

简而言之，请检查您的conf文件。路径错误

“ ICMP端口无法访问”-无法通过JDBC连接到HIVE数据库（使用KERBEROS）
