Could you add documentation about this to the user guide (near "Scheduling
Strategy")?
> New Scheduling strategy (On primary node - CRON )
> -------------------------------------------------
>
> Key: NIFI-401
> URL: https://issues.apache.org/jira/browse/NIFI-401
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Matthew Clarke
> Assignee: Matt Gilman
> Fix For: 1.1.0
>
> Attachments: initial prototype .png
>
>
> Currently the only scheduling strategy supported when a processor is set to
> use "On primary Node" is Timer Driven. There should be a second option to
> allow cron driven On primary Node scheduling strategy. This would allow
> users to more control over when a given primary node only processor runs.
> This would prevent these processors from running when configuration changes
> or instance restarts occur.
