How to fix Keberos Authentication prompt while running Java application

I wrote a Java application to connect with hive-metastore. It works fine but when I run the jar file on Linux it asks for Kerberos Username and password . I already specified the Kerberos principal and keytab file in my code. And I don't want to use additional jass.config file. Is there any way to resolve that problem?

Here is my source code

    HiveConf conf = new HiveConf();
    MetastoreConf.setVar(conf, ConfVars.THRIFT_URIS, "thrift://HOSTNAME:9083");
    MetastoreConf.setBoolVar(conf, ConfVars.USE_THRIFT_SASL, true);
    MetastoreConf.setVar(conf, ConfVars.KERBEROS_PRINCIPAL, "hive/HOSTNAME@example.com");
    MetastoreConf.setVar(conf, ConfVars.KERBEROS_KEYTAB_FILE, "hive.keytab");
    System.setProperty("java.security.krb5.realm", "EXAMPLE.COM");
    System.setProperty("java.security.krb5.kdc", "HOSTNAME");
    System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
    HiveMetaStoreClient client = new HiveMetaStoreClient(conf);
    client.close();     

Expected Result- It should verify the connection successfully

Actual result-

java -jar Application

Kerberos username [root]: Kerberos password [root]:

I want to bypass this kerberos terminal prompt authentication. Is there any way to do that?

          final String user = "hive/HOSTNAME@EXAMPLE.COM";
          final String keyPath = "hive.keytab";
          Configuration conf = new Configuration();
          System.out.println("In case of kerberos authentication");
          conf.set("hadoop.security.authentication", "kerberos");
          System.setProperty("java.security.krb5.kdc", "HOSTNAME");
          System.setProperty("java.security.krb5.realm", "EXAMPLE.COM");

          UserGroupInformation.setConfiguration(conf);
          UserGroupInformation.loginUserFromKeytab(user, keyPath);

          HiveConf conf1 = new HiveConf(); MetastoreConf.setVar(conf1,
          ConfVars.THRIFT_URIS, "thrift://HOSTNAME:9083"); HiveMetaStoreClient
          client = new HiveMetaStoreClient(conf1);
          client.close();

It works fine now
