> Need ability to clear framework state
> -------------------------------------
>
> Key: NIFI-10848
> URL: https://issues.apache.org/jira/browse/NIFI-10848
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Simon Bence
> Priority: Major
>
> We need the ability to clear the NiFi Framework's state. Currently, we store
> local state using a single Write-Ahead Log for all components, including
> framework. Users are able to right-click on a component such as a Processor
> and click "View state" and then "Clear state." However, there's no way to do
> this for the framework.
> This can be important when troubleshooting. For example, if a node is
> suddenly removed and cannot be contacted, we may want to clear all cluster
> state and restart NiFi. Currently, there's no way to do that other than to
> delete the local state directory. Deleting that directory, however, will
> clear state for all components.
> Potential options would include:
> * Separate out the storage of state into individual directories for each
> component
> * Separate out storage of state into 'framework' and 'extensions'
> * Keep state storage as-is and introduce something into toolkit that allows
> updating the write-ahead log to clear state
>
