JAAS configuration should delegate unknown application names to pre-existing \
                configuration

                 Key: HADOOP-7070
                 URL: https://issues.apache.org/jira/browse/HADOOP-7070
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 0.22.0, 0.23.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Critical


As reported here: https://issues.cloudera.org/browse/DISTRO-66 it is impossible to \
use secured Hadoop inside an application that relies on other JAAS configurations. \
This is because the static initializer of UserGroupInformation replaces the JAAS \
configuration, but we don't delegate unknown applications up to whatever \
Configuration was installed previously. The delegation technique seems to be used by \
JBoss's XMLLoginConfigImpl for example.
