To Reduce the Size of a Kerberos Ticket All Active Directory groups to which a user belongs are encoded within an issued Kerberos ticket, increasing the size of the HTTP header. Choose one of the following options to reduce the ticket's size....
二、HDFS服务集成Kerberos 1. 创建keytab文件 在集群的每个节点上面创建对应的keytab文件,用于HDFS服务各个Daemon(如NameNode/DataNode等)之间的身份认证,防止非法的节点加入集群。 E-MapReduce集群中的HDFS的所有Daemon都是在hdfs账号下启动,所以各个Daemon使用共用相同的keytab配置。
EMR 暂不支持集群创建完成后开启和关闭 Kerberos 服务。 创建用户 使用用户管理功能新建一个用户,此处以 tencent 用户为例,用户创建后 EMR 集群将自动创建此用户 principal 并加入 Kerberos 数据库中。 登录到 Master 节点,在 root 用户下,使用以下命令查看当前 principal : ...

Kerberos協議認證過程主要有以下兩個階段: 第一階段:KDC對Client進行身份認證 當用戶端使用者(Principal)訪問一個整合了Kerberos的服務之前,需要先通過KDC的身份認證。 如果身份認證通過,則用戶端會擷取到一個TGT(Ticket Granting Ticket),後續就可以使用該TGT去訪問整合了Kerberos的服務。 第二階段:Service對Client進行...
