1. Go to default hdfs repo config.
2. Add a configuration.
3. Check the admin audit log.
4. Then delete the configuration.
5. Check the admin audit log.
When adding configuration, there are some fields that are not changed recorded in the audit log. The old value and new value are all null.
When deleting the configuration, the audit log is recorded not correctly.
For example:I added only one configuration, name is "TestConfig", value is "abc". In the audit log, "TestConfig" is correctly recorded, but several other fields are also recorded, with old value and new value are all null. Then delete it, abc is recorded as the value of other fields other than "TestConfig" in audit log.
Screenshot is attached.
