我尝试使用 kerberos 配置安全 Hadoop。我已启动 KDC 服务器，生成相关密钥表并将其复制到相应节点。kerberos 可以正常工作（使用 kinit），但当我尝试启动 namenode 时，我遇到了一个奇怪的错误。我已修改 core-site.xml 和 hdfs-site.xml。
这是我的 core-site.xml
我尝试寻找答案，但没有找到合适的解决方案，如果有人能帮忙，非常感谢
这是错误日志：

但是当我尝试启动 namenode 时遇到错误
我注意到它提示：用户 hdfs/master.hadoop@HADOOP 使用 keytab 文件 /usr/local/src/hadoop-1.2.1/conf/hdfs.keytab 登录成功
但为什么这个例外，“授权 (hadoop.security.authorization) 已启用，但身份验证 (hadoop.security.authentication) 配置为简单。请配置其他方法，如 kerberos 或 digest”
