[jira] [Created] (YARN-3834) Scrub debug logging of tokens during resource localization.

Chris Nauroth created YARN-3834:
-----------------------------------

             Summary: Scrub debug logging of tokens during resource localization.
                 Key: YARN-3834
                 URL: https://issues.apache.org/jira/browse/YARN-3834
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 2.7.1
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


During resource localization, the NodeManager logs tokens at debug level to aid troubleshooting.  This includes the full token representation.  Best practice is to avoid logging anything secret, even at debug level.  We can improve on this by changing the logging to use a scrubbed representation of the token.
