hadoop - 色调文件浏览器不工作

Question

我已经安装了 hue，但 hue 中的文件浏览器无法正常工作并抛出“服务器错误 (500)”

来自 error.log 的数据

webhdfs      ERROR    Failed to determine superuser of WebHdfs at http://namenode:50070/webhdfs/v1: SecurityException: Failed to obtain user group information: org.apache.hadoop.security.authorize.AuthorizationException: User: hue is not allowed to impersonate hue (error 401)
Traceback (most recent call last):
  File "/home/hduser/huef/hue/desktop/libs/hadoop/src/hadoop/fs/webhdfs.py", line 108, in superuser
    sb = self.stats('/')
  File "/home/hduser/huef/hue/desktop/libs/hadoop/src/hadoop/fs/webhdfs.py", line 188, in stats
    res = self._stats(path)
  File "/home/hduser/huef/hue/desktop/libs/hadoop/src/hadoop/fs/webhdfs.py", line 182, in _stats
    raise ex

注意:我已将以下内容添加到 core-site.xml 并启用了 webhdfs

 <property>
                <name>hadoop.proxyuser.hue.hosts</name>
                <value>*</value>
        </property>
        <property>
                <name>hadoop.proxyuser.hue.groups</name>
                <value>*</value>
        </property>

当我尝试通过 oozie 在 hue 中访问 hdfs 文件位置时出错

An error occurred: SecurityException: Failed to obtain user group information: org.apache.hadoop.security.authorize.AuthorizationException: User: hue is not allowed to impersonate hduser (error 401)
