Subject [jira] Created: (HADOOP-6400) Log errors getting Unix UGI

Log errors getting Unix UGI

                 Key: HADOOP-6400
                 URL: https://issues.apache.org/jira/browse/HADOOP-6400
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 0.20.1, 0.21.0, 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor

For various reasons, the calls out to `whoami` and `id` can fail when trying to get the unix
UGI information. Currently it silently ignores failures and uses the default DrWho/Tardis
ugi. This is extremely confusing for users - we should log the exception at warn level when
the shell execs fail.
