可以通过直线连接到配置单元，但不能连接到java。错误无法使用JDBC打开客户端传输Uri GSS启动失败

Question

我对启用了kerberos的远程hdfs集群具有访问权限。当我尝试使用直线连接时

beeline -u "jdbc:hive2://host:port/arstel;principal=principal" 

连接成功。

但是，当我写一个Java应用程序，并使用相同的JDBC开放的，我得到

ERROR transport.TSaslTransport: SASL negotiation failure 
javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)] 
Caused by: GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt) 
jdbc.HiveConnection: Could not open client transport with JDBC Uri: jdbc:hive2://host:port/arstel;principal=principal 
Exception in thread "main" java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://host:port/arstel;principal=principal: GSS initiate failed 
Caused by: org.apache.thrift.transport.TTransportException: GSS initiate failed 

我的应用程序

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

public static void main(String[] args) throws SQLException, ClassNotFoundException { 
    Class.forName(driverName); 
    Connection con = DriverManager 
        .getConnection("jdbc:hive2://host:port/arstel;principal=principal"); 
    Statement stmt = con.createStatement(); 
    String tableName = "evkuzmin_testHiveDriverTable"; 
    stmt.execute("drop table if exists " + tableName); 
    stmt.execute("create table " + tableName + " (key int, value string)"); 
    } 
} 

为什么会发生这种情况，我怎么能解决呢？

我也试过这个。同样的结果。

getConnection("jdbc:hive2://host:port/arstel;principal=principal;" + 
             "auth=kerberos;" + 
             "kerberosAuthType=fromSubject"); 

编辑

我没有密钥表。在阅读了堆栈和here后，我创建了一个指令。然后，我添加属性，以我的Java文件，这样

Class.forName(driverName); 
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"); 

后，我加入到resources

GSS-的Jaas.conf

com.sun.security.jgss.initiate { 
    com.sun.security.auth.module.Krb5LoginModule=required 
    useKeyTab=true 
    useTicketCache=false 
    principal="hive/[email protected]" 
    doNotPrompt=true 
    keyTab="EvKuzmin.keytab" 
    debug=true; 
} 

和krb5.conf的

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

[realms] 
DOMAIN = { 
    admin_server = ms-dcs.DOMAIN 
    kdc = ms-dcs.DOMAIN 
} 

[domain_realm] 
.DOMAIN = DOMAIN 
DOMAIN = DOMAIN 

然后错误改变了

java.sql.SQLException: Could not create secure connection to jdbc:hive2://host:port/arstel;principal=hive/principal;auth=kerberos;kerberosAuthType=fromSubject: Failed to open client transport 
Caused by: javax.security.sasl.SaslException: Failed to open client transport [Caused by java.io.IOException: Could not instantiate SASL transport] 
Caused by: java.io.IOException: Could not instantiate SASL transport 
Caused by: javax.security.sasl.SaslException: Failure to initialize security context [Caused by GSSException: Invalid name provided (Mechanism level: Cannot locate default realm)] 
Caused by: GSSException: Invalid name provided (Mechanism level: Cannot locate default realm) 

ALSO

有alrady这里密钥表

Keytab name: FILE:/etc/krb5.keytab 

但我不知道什么是它的领域或如何使用它+我没有访问该文件夹。

尝试通过UserGroupInformation进行操作。遇到错误

Exception in thread "main" java.lang.IllegalArgumentException: Invalid attribute value for hadoop.security.authentication of Kerberos 
     at org.apache.hadoop.security.UserGroupInformation.initialize(UserGroupInformation.java:200) 
     at org.apache.hadoop.security.UserGroupInformation.setConfiguration(UserGroupInformation.java:227) 
     at com.hive.connect.controller.RecordController.main(RecordController.java:20) 

EDIT3 2017年8月10日 使用用户组

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

    public static void main(String[] args) throws SQLException, ClassNotFoundException, IOException { 
    Configuration conf = new Configuration(); 
    conf.set("hadoop.security.authentication", "kerberos"); 
    UserGroupInformation.setConfiguration(conf); 
    UserGroupInformation.loginUserFromKeytab("hive/principal", "EvKuzmin.keytab"); 
    Class.forName("org.apache.hive.jdbc.HiveDriver"); 
    Connection con = DriverManager 
         .getConnection("jdbc:hive2://host:port/arstel;" + 
              "principal=hive/principal;" + 
              "tez.queue.name=adhoc;" + 
              "hive.execution.engine=tez;" + 
              "mapreduce.job.reduces=1;"); 

错误

java.io.IOException: Login failure for hive/principal from keytab EvKuzmin.keytab 
    at org.apache.hadoop.security.UserGroupInformation.loginUserFromKeytab(UserGroupInformation.java:695) 
    at com.hive.connect.controller.RecordController.main(RecordController.java:22) 
Caused by: javax.security.auth.login.LoginException: Unable to obtain password from user

最后，我改变了我的krb5。CONF看起来像这样

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

[realms] 
DOMAIN = { 
    admin_server = ms-dcs.DOMAIN 
    kdc = ms-dcs.DOMAIN 
} 

[domain_realm] 
.DOMAIN = DOMAIN 
DOMAIN = DOMAIN 

我的Java代码

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

    public static void main(String[] args) throws SQLException, ClassNotFoundException, IOException { 
    Class.forName(driverName); 
    System.setProperty("javax.security.auth.useSubjectCredsOnly","false"); 
    System.setProperty("java.security.krb5.conf","krb5.conf"); 

    Connection con = DriverManager 
         .getConnection("jdbc:hive2://host:port/arstel;" + 
              "principal=hive/[email protected];" + 
              "auth=kerberos;" + 
              "kerberosAuthType=fromSubject");

当我启动群集我不需要输入密码和登录，而是在本地机器上我做的窗户。
