Summary: Logging Enhancement for HTTPS Address Configuration in
JournalNodeHttpServer
Key: HDFS-17617
URL: https://issues.apache.org/jira/browse/HDFS-17617
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Affects Versions: 3.3.6
Environment: Version: {{`3.3.6`}}
Location:
{{{}`hadoop/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/qjournal/server/JournalNodeHttpServer.java`{}}},
in {{`start`}} method. Lines 61-74
Reporter: LoggingResearch
Attachments: TestJournalNode.java, original-vs-log-enhanced.md
This case focuses on adding logging to the {{start}} method of the
{{JournalNodeHttpServer}} class to provide better visibility into how the HTTPS
address is configured. The original code does not log critical information
related to the HTTPS address configuration, which can make troubleshooting
difficult, especially in cases where the address is overridden by the bind host
or left as a default value.
*Expected Behavior:*
The system should log whether the HTTPS address is being overridden by the bind
host or if the default value is being used. Additionally, any misconfigurations
or null values should be logged as errors.
*How-to-Fix:* Enhance the {{start}} method to include logging statements that
detail the configuration and any potential issues with the HTTPS address setup.
