当SparkR后端处理程序冻结时，除了杀死纱线应用程序外，我无能为力了……这是它自己的stackoverflow问题……但是今天，当我尝试时，这是我第一次遇到错误sudo并终止该应用程序：
[me@myserver ~]$ sudo yarn application -kill application_1536084816396_0023
18/09/10 15:27:37 INFO client.AHSProxy: Connecting to Application History

Killing application application_1536084816396_0023
Exception in thread "main" org.apache.hadoop.yarn.exceptions.YarnException:
java.security.AccessControlException: User hdfs cannot perform
operation MODIFY_APP on application_1536084816396_0023
为什么sudo将我解释为hdfs用户？我的yarn.admin.acl设置为dr.who,activity_analyzer,yarn ...曾经用来解决问题，看起来好像没有更改。
