我们正在尝试为SAS Hadoop数据加载器（DLH）配置IWA。 SAS服务器在Active Directory域下运行，并且SSO已成功配置。我们需要配置DLH，以使用客户端生成的票证与Hortonworks Hadoop MIT Kerberos进行通信。该功能不起作用。
因此，基本上，我们在AD（ABC.COM）和Hadoop MIT Kerberos（xyz-Hadoop领域名称没有任何FQDN，而且都是小写字母）2方法信任建立中存在问题。我们已经按照以下链接（https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.0/bk_security/content/kerb-config-realm-kdc.html）确认了信任关系，并且一切正常，但是以某种方式使用AD的HTTP票证，我们无法登录到hadoop并收到以下错误消息：
com.sas.svcs.dm.hadoop.spi.exception.HadoopConfigurationException：无法找到GSSCredential。检查Kerberos配置
我们已经尝试了很多故障排除方法。现在终于可以确定我们之间存在信任问题，并测试以下要求执行的步骤。
在SAS服务器（Linux）上
kinit -f HTTP/xxx.abc.com@ABC.COM
klist -eaf
kvno hive/xyz@xyz
如果上述所有步骤均有效，则表明我们已启用信任
这是我们看到的错误
kvno：获取hive / xyz @ xyz的凭据时，KDC返回错误字符串：PROCESS_TGS
和
kvno：获取hive / xyz @ xyz的凭据时，解密完整性检查失败
kinit -f HTTP/xxx.abc.com@ABC.COM (this works fine)
# kinit -k -t xxx.host.keytab HTTP/xxx.abc.com@ABC.COM

ksetup /SetEncTypeAttr xyz DES-CBC-CRC DES-CBC-MD5 RC4-HMAC-MD5 AES128-CTS-HMAC-SHA1-96 AES256-CTS-HMAC-SHA1-96

答案 0 :(得分：0)
问题出在AD上，而Hadoop Trust无法正常工作。因此，在故障排除期间，我在AD的Hadoop Principal上添加了enctypes。我在其中一个网站上找到了以下说明
“主体（帐户）是使用系统默认的enctype创建的。更改密码时，还必须重新创建主体，或至少更新主体的密码。”
所以，我重置了密码
netdom trust xyz /Domain:ABC.COM / reset / realm / passwordt：xxxxXXXxxxx
此外，KVNO在AD和Hadoop之间没有多余的匹配，所以我在Hadoop端更新了kvno
在Hadoop服务器上重新启动以下服务
/ sbin / service krb5kdc重新启动 / sbin / service kadmin重新启动
还有Voila ...我能够运行kvno命令。
