我们最近使用 CDH 5 (2.3.0-cdh5.1.3) 部署了 YARN，集群正在运行文件，作业也在运行。但是，如果作业完成（成功/失败），我们无法从资源管理器 UI 访问日志，我们会收到以下错误

Failed redirect for container_1412716537481_0322_01_000001
Failed while trying to construct the redirect url to the log server. Log Server url may not be configured
Container does not exist.

运行作业也有一些例外：

hdfs://user/history/ 的适当权限是什么？

有人有同样的问题吗？

我认为您的集群是安全的（启用了 Kerberos），并且对于安全环境中的 HTTP 身份验证，您需要设置以下参数。参考 http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.6.0/ds_Hadoop/hadoop-project-dist/hadoop-common/HttpAuthentication.html
