我尝试使用Kerberosconfiguration安全的hadoop。 我已经启动了KDC服务器，生成并复制相关的keytab到相应的节点。 kerberos可以正常工作（使用kinit），但是当我尝试启动namenode时，我插入一个奇怪的错误。 我修改了core-site.xml和hdfs-site.xml。
这里是我的core-site.xml
我试图寻找答案，但没有find一个合适的解决scheme，如果有人可以帮助，非常感谢
这里是错误日志：

但是当我尝试启动namenode时遇到错误
我注意到它提示：login成功的用户hdfs / master.hadoop@HADOOP使用keytab文件/usr/local/src/hadoop-1.2.1/conf/hdfs.keytab
但是为什么这个例外， “授权（hadoop.security.authorization）被启用，但authentication（hadoop.security.authentication）configuration为简单的，请configuration另一种方法，如kerberos或摘要”
