Eric Payne resolved HDFS-7362. ------------------------------ Resolution: Duplicate This is not exactly a dup of HADOOP-10817, but changes made for HADOOP-10817 fixed this issue. > 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)
