Summary: Exposing Password Retrieval Process for Web Application
Utilities in method `getPassword`
Key: YARN-11726
URL: https://issues.apache.org/jira/browse/YARN-11726
Project: Hadoop YARN
Issue Type: Improvement
Components: yarn
Affects Versions: 3.3.6
Environment: Version: {{3.3.6}}
Location:
{{{}hadoop/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/java/org/apache/hadoop/yarn/webapp/util/WebAppUtils.java{}}},
in the {{getPassword}} method, lines 486-500.
Reporter: LoggingResearch
Attachments: TestWebAppUtils.java, original-vs-log-enhanced.md
The method {{getPassword}} in {{WebAppUtils}} is responsible for securely
retrieving passwords from the configuration based on the provided alias. If the
alias is not set or if there's an issue during the retrieval, the system
currently fails silently. Enhancing the logging within this method will provide
more transparency and help diagnose configuration issues, such as missing or
incorrect password aliases.
*Expected Behavior:*
The system should log the success or failure of password retrieval attempts,
including any issues encountered during the process. This will improve
traceability and allow administrators to more easily identify and correct
misconfigurations or errors related to password management.
*How-to-Fix:*
We propose adding log statements to expose the success or failure of password
retrieval operations. This will enhance the visibility of configuration-related
issues, allowing administrators to better manage security credentials within
YARN.
