> Implement Standard Logging for Deprecated Features
> --------------------------------------------------
>
> Key: NIFI-9374
> URL: https://issues.apache.org/jira/browse/NIFI-9374
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework, Extensions
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Major
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> Over the course of multiple releases and numerous capability improvements,
> various areas of the code have become deprecated. Deprecated classes,
> methods, and properties are required to maintain compatibility when upgrading
> between minor releases, but it can be difficult for both developers and users
> to track all uses of deprecated features.
> Following the pattern of other libraries and frameworks, the purpose of this
> issue is to implement standard logging for deprecated features. The default
> logging configuration should include a new log file dedicated to deprecated
> usage patterns. The implementation should wrap standard SLF4J logging and
> provide a common standard for logger names. This approach should make it easy
> to add deprecation log warnings throughout the application, and also make it
> easy for users to determine whether their configuration is using deprecated
> features.
> Having a dedicated log for deprecated features will provide a straightforward
> method of determining whether a given NiFi installation can be upgraded to
> future major releases.
