我正在尝试使用kerberos保护我的hdp2hadoop集群。
到目前为止，hdfs、hive、hbase、hue beeswax和hue job/task浏览器工作正常；但是，hue的文件浏览器不工作，它会回答：
WebHdfsException at /filebrowser/
AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS] (error 500)
Request Method: GET
Request URL: http://bt1svlmy:8000/filebrowser/
Django Version: 1.2.3
Exception Type: WebHdfsException
Exception Value:
AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS] (error 500)
Exception Location: /usr/lib/hue/desktop/libs/hadoop/src/hadoop/fs/webhdfs.py in _stats, line 208
Python Executable: /usr/bin/python2.6
Python Version: 2.6.6
(...)我的 hue.ini 文件配置为所有 security_enabled=true 以及其他相关参数的设置。
我相信问题在于webhdfs。
我试过了在http://hadoop.apache.org/docs/r1.0.4/webhdfs.html#authentication
curl -i --negotiate -L -u : "http://172.19.115.50:14000/webhdfs/v1/filetoread?op=OPEN"答案：

curl --negotiate -i -L -u: "http://172.19.115.50:14000/webhdfs/v1/filetoread?op=OPEN&user.name=theuser"它回答：

{"RemoteException":{"message":"SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS]","exception":"AccessControlException","javaClassName":"org.apache.hadoop.security.AccessControlException"}}webhdfs和curl之间似乎没有kerberos协商。
我期待的是：

A|1|2|3
B|4|5|6知道哪里出了问题吗？
我的脑子里有 hdfs-site.xml 在每个节点上：
<property>
<name>dfs.webhdfs.enabled</name>
<value>true</value>
</property>
<property>
<name>dfs.web.authentication.kerberos.principal</name>
<value>HTTP/_HOST@MY-REALM.COM</value>
</property>
<property>
<name>dfs.web.authentication.kerberos.keytab</name>
<value>/etc/hadoop/conf/HTTP.keytab</value> <!-- path to the HTTP keytab -->
</property>

看起来您不访问webhdfs（默认端口=50070），而是访问httpfs（默认端口=14000），这是一个“普通”的webapp，其安全性不同。
webhdfs的url通常类似于
http://namenode:50070/webhdfs/v1; 尝试使用该参数修改hue.ini（建议使用webhdfs而不是httpfs）
