[jira] Updated: (HADOOP-7189) Add ability to enable 'debug' property in JAAS configuration

     [ https://issues.apache.org/jira/browse/HADOOP-7189?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon updated HADOOP-7189:
--------------------------------

    Attachment: enable-UGI-debug-example.txt

this isn't a patch meant to actually be committed - but just shows the debug setting I'm talking about. This should be made conditional by a Java property or env var.

> Occasionally users have run into weird "Unable to login" messages. Unfortunately, JAAS obscures the underlying exception message in many cases because it thinks leaking the exception might be insecure in itself. Enabling the "debug" option in the JAAS configuration gets it to dump the underlying issue and makes troubleshooting this kind of issue easier.
