Eric Payne created HDFS-7362: -------------------------------- Summary: Proxy user refresh won't modify or remove existing groups or hosts from super user list Key: HDFS-7362 URL: https://issues.apache.org/jira/browse/HDFS-7362 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.5.0 Reporter: Eric Payne Assignee: Eric Payne
2.x added a new DefaultImpersonationProvider class for reading the superuser configuration. In this class, once the host and group properties for a proxyuser are defined, they cannot be removed or modified without bouncing the daemon. As long as the config is updated correctly the first time, this problem won't manifest itself. Once defined, these properties don't tend to change. However, if the properties are mis-entered the first time, restarting the NN/RM/JHS/etc will be necessary to correctly re-read the config. An admin refresh won't do it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
