---------------------------------------
Summary: add a method to UserGroupInformation to load settings
from a given conf file
Key: HADOOP-10559
URL: https://issues.apache.org/jira/browse/HADOOP-10559
Project: Hadoop Common
Issue Type: Improvement
Components: security
Affects Versions: 2.4.0
Reporter: Steve Loughran
There's no easy way to set up the security parameters of a process unless it's
set in core-site.xml, because it's just inited via:
{{initialize(new Configuration(), false);}}
# If it is defined in an XML resource injected in to the config resource list
via {{Configuration.addResource()}} -then it *may* get picked up, but only if
nothing has already created the configs.
# If it is defined in any other means -you can't get it in.
This is an issue with client apps that don't have core-site XML files on their
classpath, and which are loading their configs more dynamically. Everything
works on an insecure cluster, but try to target a secure one and things break.
