-----------------------------------
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.
