--------------------------------
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.
